Surah Yusuf begins by pointing to the Quran as a clear Book. Its words are not confusion, darkness, or random storytelling. They are signs from Allah that clarify truth for the heart.

The letters at the beginning remind us that the Quran is made of familiar letters, yet no human can produce anything like it. The story that follows is not ordinary history. It is guidance wrapped inside a powerful life story.

Allah tells us that the Quran was sent down in Arabic so that its first audience could understand it clearly. The Quran is meant to be understood, reflected upon, and lived.

This ayah reminds us that learning the Quran is not only about reading sounds. It is also about opening the mind and heart to the meanings Allah revealed.

Allah calls the story of Yusuf, peace be upon him, the best of stories. It is not just because the story is beautiful, but because it contains guidance for faith, family pain, jealousy, patience, temptation, leadership, forgiveness, and trust in Allah’s plan.

The Prophet Muhammad, peace be upon him, did not know this story in detail before revelation. Allah revealed it as truth, comfort, and guidance.

The story begins with a dream. Young Yusuf, peace be upon him, tells his father Ya‘qub, peace be upon him, that he saw eleven stars, the sun, and the moon prostrating to him.

This dream was not ordinary. It was a sign of Yusuf’s future honor, but it also became the beginning of a long test involving jealousy, separation, patience, and Allah’s hidden plan.

Ya‘qub, peace be upon him, understands that the dream is important, so he advises Yusuf not to share it with his brothers. He sees the danger of jealousy before it becomes open harm.

This ayah teaches wisdom in sharing blessings. Not every dream, plan, or gift should be announced to everyone. Shaytan can use jealousy to create harm even inside families.

Ya‘qub, peace be upon him, understands that Yusuf’s dream points toward Allah choosing him for something great. Yusuf will be taught deep understanding, including interpretation of dreams and events.

This ayah shows that Allah’s favour often unfolds through a long process. Yusuf’s future honour is promised, but the path will pass through hardship before the wisdom becomes visible.

Allah tells us that the story of Yusuf and his brothers contains signs for people who truly ask and reflect. This is not only a family story. It is a mirror for jealousy, patience, trust, forgiveness, and Allah’s hidden planning.

The phrase “for those who ask” teaches us to approach the story actively. The Quran gives deeper lessons to hearts that come seeking guidance.

Yusuf’s brothers felt that their father loved Yusuf and his brother more than them. Instead of dealing with their feelings honestly, they allowed jealousy to speak for them.

They judged their father harshly and saw themselves as more deserving because they were a strong group. This is how envy begins to twist perception: it makes love look like injustice and turns family into competition.

The brothers’ jealousy becomes a dangerous plan. They think removing Yusuf will make their father love them more.

Even more dangerously, they tell themselves they can commit a major sin now and become righteous later. This is one of Shaytan’s traps: “Do wrong now, fix yourself later.”

One brother tries to reduce the harm by stopping the plan to kill Yusuf. He suggests throwing Yusuf into a well so travellers may take him away.

This ayah shows a painful reality: sometimes people do not stop evil completely, but only make it less severe. Still, Allah’s plan was already moving through even this broken decision.

Yusuf’s brothers begin their plan by speaking gently to their father. They present themselves as sincere and trustworthy, even though their hearts are hiding jealousy.

This ayah teaches that words can sound caring while intentions are dangerous. A believer should value good speech, but also ask Allah for wisdom to see what is behind it.

The brothers make their request sound innocent. They say Yusuf will play, enjoy himself, and be protected by them.

This shows how a harmful plan can be wrapped in friendly language. The promise of protection becomes part of the deception.

Ya‘qub, peace be upon him, expresses his sadness and fear. His heart is attached to Yusuf, and he worries that his sons may become distracted and a wolf may harm him.

His words also show a father’s deep concern. But the brothers will later use this very fear as part of their false excuse.

The brothers respond with confidence in their strength. They say that if a wolf could harm Yusuf while they were present, they would truly be failures.

The tragedy is that the danger was not the wolf outside. It was the jealousy inside their own hearts.

The brothers finally carry out their plan and place Yusuf in the hidden depth of the well. To them, this looked like the end of Yusuf’s place in the family.

But Allah revealed comfort to Yusuf: one day he would remind them of this action while they would not recognize him. The well was not the end. It was the beginning of Allah’s hidden plan.

The brothers return at night, crying. Their tears are part of their false story, not proof of truth.

This ayah teaches that emotion can be used to hide wrongdoing. Tears may show pain, but they do not always prove innocence.

The brothers present the exact excuse their father had feared: the wolf ate Yusuf. They also add emotional pressure by saying he will not believe them even if they are truthful.

This ayah shows how lies often borrow from truth. They took Ya‘qub’s own fear and turned it into their false story.

The brothers bring Yusuf’s shirt with fake blood. Ya‘qub, peace be upon him, sees through the story and understands that their own souls have beautified this action for them.

His response is one of the most powerful lessons in the Quran: beautiful patience. This means patience without rebellion against Allah, without ugly complaint, and with complete reliance on Allah for help.

A caravan arrives at the well, and the water-drawer discovers Yusuf. What looked like abandonment now becomes movement toward a new chapter.

The people hide Yusuf as merchandise, treating him like a thing to profit from. But Allah knows exactly what they are doing, and His plan continues above their actions.

Yusuf, peace be upon him, is sold for a cheap price. People who did not know his true worth treated him as something small and disposable.

This ayah teaches that human beings may undervalue what Allah has honoured. Yusuf’s price in the market was low, but his rank in Allah’s plan was high.

Yusuf, peace be upon him, reaches Egypt after being sold cheaply. But Allah places him inside an important household, where his future begins to unfold.

People thought they were buying and selling Yusuf, but Allah was arranging his rise. This ayah teaches that Allah’s plan works above human plans, even when people do not realize it.

As Yusuf, peace be upon him, grew into maturity, Allah gave him wisdom and knowledge. His hardship did not waste him. It prepared him.

The ayah connects Yusuf’s rise with ihsan. Allah rewards those who do good beautifully, even when their journey is full of hidden pain.

Yusuf, peace be upon him, faces a severe private test. The doors are locked, the pressure is strong, and the temptation is direct.

His first response is not argument or pride. He says, “I seek refuge in Allah.” This ayah teaches that purity begins by running to Allah before desire takes control.

This ayah shows the seriousness of the test. Yusuf, peace be upon him, was human, but Allah protected him through clear proof and sincere servitude.

The lesson is not to trust your own strength against temptation. The safest heart is the one Allah protects. Sincerity becomes a shield when desire becomes intense.

Yusuf, peace be upon him, runs toward the door to escape the sin. She pulls him from behind and tears his shirt. Then suddenly her husband appears at the door.

Instead of admitting guilt, she immediately accuses Yusuf. This shows how sin can quickly become false accusation when a person wants to protect their image.

Yusuf, peace be upon him, speaks the truth clearly: she was the one who tried to seduce him. Then a witness from her family gives a practical way to judge the matter.

If the shirt was torn from the front, it would support her claim. This teaches that truth is supported by evidence, not just emotion or status.

The witness completes the reasoning. If Yusuf’s shirt was torn from behind, it means he was running away and she was pulling him back.

This ayah teaches that Allah can make even a torn shirt speak for the innocent. Evidence may appear small, but Allah can use it to expose truth.

When the husband sees the shirt torn from behind, the evidence becomes clear. Yusuf, peace be upon him, was innocent.

The ayah shows that truth can emerge through small details. The one who was accused becomes cleared by the very sign the situation produced.

Yusuf is told to leave the matter and not speak further about it. The woman is told to seek forgiveness because the evidence has shown her guilt.

This ayah shows that some households may choose to hide scandal rather than deal deeply with injustice. Yusuf is innocent, yet his test is not over.

The matter spreads in the city. The women speak about the wife of Al-‘Aziz and criticize her for being deeply overcome by desire for Yusuf.

This ayah shows how private sin can become public talk. It also shows how people may criticize another person while their own hearts may not be safe from the same weakness.

When the wife of Al-‘Aziz hears the women speaking about her, she arranges a gathering and makes Yusuf, peace be upon him, appear before them.

The women are so overwhelmed by Yusuf’s beauty that they cut their hands without realizing it. This shows the strength of Yusuf’s test: he was not only beautiful, but also surrounded by attention, pressure, and temptation.

The wife of Al-‘Aziz openly admits that she tried to seduce Yusuf, but he protected himself. Instead of repenting, she threatens him with prison and humiliation.

This ayah shows that sometimes refusing sin does not bring immediate comfort. It may bring pressure, threats, and worldly difficulty. But Allah sees the servant who chooses purity.

Yusuf, peace be upon him, chooses prison over sin. He does not act like he is invincible. He asks Allah to turn their plotting away from him.

This is a powerful lesson in humility. Even a prophet asks Allah for protection from temptation. Real strength is not pretending weakness does not exist. Real strength is running to Allah with it.

Allah answers Yusuf’s dua and protects him from their plotting. Allah heard his prayer and knew the pressure surrounding him.

This ayah teaches that no private struggle is hidden from Allah. When a servant sincerely seeks protection, Allah can turn away harm in ways the servant cannot control.

Even after the signs of Yusuf’s innocence became clear, they still decided to imprison him. This was not justice. It was image management and pressure from power.

This ayah teaches that innocence does not always protect a person from unfair systems immediately. But Allah’s plan continues even through prison doors.

Two young men enter prison with Yusuf and ask him to interpret their dreams. Even inside prison, Yusuf is known for ihsan, goodness, and excellent character.

This shows that a believer’s character should not depend on location. Yusuf was excellent in the palace, and he remained excellent in prison.

Before answering their dreams, Yusuf, peace be upon him, points the gift back to Allah. He does not present his knowledge as personal greatness.

He uses the moment to begin dawah. Even in prison, he teaches Tawheed and separates himself from disbelief and denial of the Hereafter.

Yusuf, peace be upon him, explains that he follows the way of the prophets before him: Ibrahim, Ishaq, and Ya‘qub. Their way is Tawheed, worshipping Allah alone.

He calls Tawheed a favour from Allah. Guidance is not something to be treated casually. It is a mercy that deserves gratitude.

Yusuf, peace be upon him, calls his prison companions gently and asks them a clear question: is it better to worship many powerless lords, or Allah alone?

This ayah teaches the simplicity and strength of Tawheed. One Lord brings clarity. Many false lords bring confusion, fear, and divided loyalty.

Yusuf, peace be upon him, explains that false gods are only names invented by people and inherited from their fathers. They have no authority from Allah.

He then gives the core of faith: judgment belongs only to Allah, and worship belongs only to Him. This is the straight religion, even if many people do not understand it.

Yusuf, peace be upon him, explains the dreams of the two prisoners. One will return to serving his master, while the other will face execution.

This ayah shows that Yusuf’s knowledge was serious and truthful. He did not soften the truth to please people. He delivered the interpretation clearly, while still guiding them toward Allah.

Yusuf, peace be upon him, asks the prisoner who would be freed to mention his case to the king. This was a normal worldly means of seeking release.

But Shaytan caused the man to forget, and Yusuf stayed in prison for several more years. This teaches that even when people forget you, Allah has not forgotten you. Delay can still be part of Allah’s perfect plan.

The king sees a powerful dream: seven fat cows eaten by seven lean cows, and seven green ears of grain along with dry ones.

This dream becomes the door Allah uses to bring Yusuf out of prison. What looked like a king’s concern was actually part of Allah’s plan to raise Yusuf and save a nation from crisis.

The king’s chiefs dismiss the dream as confused dreams and admit they do not know its interpretation.

This ayah shows that position and status do not guarantee knowledge. Sometimes the answer is not with the people near power, but with someone hidden away by Allah’s plan.

The former prisoner finally remembers Yusuf after a long time. The king’s dream becomes the reason he recalls the one he had forgotten.

This ayah teaches that a delayed memory can still arrive at the exact time Allah wants. What people forget may return when Allah decides the next door should open.

The former prisoner comes to Yusuf and calls him “As-Siddiq”, the very truthful one. Even after years in prison, Yusuf’s truthfulness is still remembered.

This ayah shows the value of consistent character. Yusuf’s reputation for truth becomes the bridge through which Allah opens the next stage of his life.

Yusuf, peace be upon him, does more than interpret the dream. He gives a practical economic plan: cultivate for seven productive years, preserve the grain, and consume only a little.

This ayah teaches that wisdom includes planning, saving, and preparing before hardship arrives. Tawakkul does not mean carelessness. It means trusting Allah while acting wisely.

Yusuf explains that after seven years of abundance, seven difficult years will come. The stored grain will protect the people from famine.

This ayah teaches that hardship becomes easier when people prepare with discipline and wisdom. A believer should not waste today’s blessing while ignoring tomorrow’s need.

After the difficult years, Yusuf gives hope: relief will come. Rain will return, crops will grow, and people will press fruits and produce again.

This ayah is a gentle reminder that hardship is not always the final chapter. Allah can bring relief after long seasons of struggle.

The king asks for Yusuf to be brought out, but Yusuf does not rush out of prison. He asks for the truth about the women to be investigated first.

This shows Yusuf’s dignity. He does not want freedom while his reputation remains stained. He wants his innocence clarified openly, because honour and truth matter.

The king investigates the matter, and the women admit that they know no evil against Yusuf, peace be upon him. Then the wife of Al-‘Aziz openly confesses that she was the one who tried to seduce him.

This ayah shows how Allah brings truth out, even after years of silence. Yusuf’s patience was not wasted. His innocence became clear publicly.

This ayah highlights the importance of loyalty when no one is watching. Yusuf, peace be upon him, wanted his innocence known and betrayal rejected.

Allah does not bless the plots of those who betray trust. Deception may seem clever for a moment, but it does not receive true guidance from Allah.

This ayah teaches deep humility about the human soul. The nafs can push a person toward evil unless Allah protects that person with mercy.

No one should feel completely safe from temptation. Safety comes from Allah’s mercy, forgiveness, and constant protection.

After Yusuf’s innocence becomes clear, the king calls him and recognizes his value. Yusuf moves from prison to a position of honour and trust.

This ayah shows how Allah can change a person’s situation completely. Years of patience, truthfulness, and excellence now become visible to those in power.

Yusuf, peace be upon him, asks to be placed over the storehouses because he knows he has the ability, honesty, and knowledge needed for the coming crisis.

This ayah teaches that seeking responsibility is allowed when a person is qualified, trustworthy, and doing it for public benefit, not ego.

Allah establishes Yusuf in Egypt. The one who was thrown into a well and sold cheaply is now trusted with authority in the land.

This ayah repeats a beautiful principle: Allah does not waste the reward of the muhsinin. Excellence during hardship becomes a seed Allah can grow into honour.

Even though Yusuf receives honour in this world, Allah reminds us that the reward of the Hereafter is better for believers who have taqwa.

This ayah keeps the heart balanced. Worldly success can be a mercy, but the greater success is with Allah in the next life.

Yusuf’s brothers come to Egypt seeking food during the difficult years. They stand before the very brother they once threw into the well.

Yusuf recognizes them, but they do not recognize him. Allah has turned the situation completely: the one they tried to remove is now the one they need.

Yusuf gives his brothers their provisions and asks them to bring their younger brother from their father next time. He does this as part of a wise plan to reunite the family and reveal truth at the right time.

He reminds them that he has treated them with full measure and good hospitality. Even with people who wronged him, Yusuf acts with control, strategy, and dignity.

Yusuf makes it clear that they must bring their younger brother if they want provisions again. This creates a serious condition that will bring the next part of Allah’s plan forward.

This ayah teaches that wise boundaries can be necessary. Yusuf is not acting randomly. He is guiding events carefully toward truth, reunion, and healing.

The brothers promise Yusuf, peace be upon him, that they will try to convince their father to send their younger brother with them.

This moment begins another test for Ya‘qub, peace be upon him. The same sons who once took Yusuf away now need to ask for another beloved son.

Yusuf, peace be upon him, secretly returns their payment into their bags. This kindness is also part of his wise plan to encourage them to come back.

He has power over them, yet he gives generously. This shows controlled strength, hidden mercy, and careful planning.

The brothers return to Ya‘qub, peace be upon him, and explain that they will not receive more provisions unless they bring their younger brother.

They again promise protection. But for Ya‘qub, this promise carries painful memories because they once made similar claims about Yusuf.

Ya‘qub, peace be upon him, remembers what happened to Yusuf and questions whether he can trust them again. His pain is still alive.

Yet he places his trust in Allah, not in their promise alone. He knows Allah is the best guardian and the most merciful.

The brothers discover that their payment has been returned. They use this as another reason to convince their father to send their younger brother.

They see benefit, provision, and an extra measure of grain. But Ya‘qub’s concern is not only food. His concern is trust, safety, and the memory of Yusuf.

Ya‘qub, peace be upon him, agrees only after they give a serious pledge by Allah. He sets a clear condition and makes Allah witness over their words.

This ayah teaches that trust does not mean carelessness. A believer can rely on Allah while also taking serious precautions.

Ya‘qub, peace be upon him, advises his sons to enter Egypt through different gates. This was a practical precaution, possibly to avoid attention, harm, or envy.

But he also makes it clear that precautions cannot override Allah’s decree. This is true tawakkul: take the means, but know that the final command belongs only to Allah.

The brothers follow Ya‘qub’s advice and enter from different gates. But Allah reminds us that this precaution itself could not stop Allah’s decree.

Ya‘qub’s advice came from knowledge and care, but he still knew the final outcome belonged to Allah. This is the balance of wisdom and surrender.

When the brothers return with the younger brother, Yusuf privately brings him close and reveals who he is. This is a tender moment after years of separation.

He comforts his brother and tells him not to grieve over what the others used to do. Yusuf is not controlled by bitterness. He is guided by mercy, wisdom, and Allah’s plan.

Yusuf places the drinking cup in his younger brother’s bag as part of a plan that will allow his brother to remain with him. Then a caller announces that something has been stolen.

This scene may feel tense, but it is moving within Allah’s larger wisdom. The story is now drawing the family closer to the truth that has been hidden for years.

When the caller accuses the caravan of theft, the brothers turn back and ask what is missing. They do not yet understand that the situation is part of a larger plan.

This moment begins a tense test. The brothers are now being pulled into a situation that will expose their character, their past, and their ability to keep their promise.

The officials announce that the king’s measuring cup is missing. They also promise a reward: a camel-load of grain for the one who brings it.

This increases the seriousness of the matter. The accusation is not small, because the missing item belongs to the king’s administration.

The brothers strongly deny the accusation. They swear by Allah and say that their behavior has shown they did not come to cause corruption or steal.

There is irony here. They deny theft now, but they once committed a far deeper betrayal against Yusuf. The story slowly brings old wounds back into the light.

The officials ask the brothers what punishment should apply if the missing cup is found with them. This question gives the brothers a chance to state the ruling themselves.

This is part of the wisdom of the situation. The brothers will be held according to the very standard they accept from their own side.

The brothers state that whoever has the cup in his bag should be kept as the penalty. This matches their own known rule and becomes the means through which Yusuf can keep his younger brother with him.

They do not realize that their answer is helping Allah’s plan unfold. What seems like a legal response becomes a step toward family reunion and truth.

The search begins with the brothers’ bags before Yusuf’s younger brother’s bag, so the matter unfolds naturally. Then the cup is found in the younger brother’s bag.

Allah explains that this was part of His plan for Yusuf. Under the king’s law, Yusuf could not have kept his brother, but Allah arranged events through another legal path. Above every knowledgeable person is Allah, the All-Knowing.

The brothers quickly distance themselves from the younger brother and even accuse Yusuf from the past. They do not know that Yusuf himself is standing before them.

Yusuf controls his emotions and keeps his response inside. This ayah shows incredible restraint. Sometimes silence is stronger than exposing everything immediately.

The brothers now plead for their younger brother. They mention their elderly father and ask Yusuf to take one of them instead.

This is different from their earlier behavior with Yusuf. The test is revealing whether they have changed, whether they now care about their father’s pain and their brother’s safety.

Yusuf refuses to take someone else in place of his younger brother. He says it would be injustice to hold a person who was not connected to the found item.

This keeps the plan within a form of justice according to the ruling they themselves accepted. Yusuf does not act out of emotional pressure, even though the brothers plead strongly.

When the brothers realize they cannot convince Yusuf to release their younger brother, they speak privately. The eldest reminds them of their pledge to their father and their earlier failure with Yusuf.

He refuses to return until his father allows him or Allah judges the matter. This shows a serious awakening of responsibility. Their old sin against Yusuf is now heavy in their memory.

The eldest brother tells the others to return to their father and explain what happened. They can only speak according to what they saw: the cup was found in their brother’s bag.

They also admit that they could not know the unseen. This is a painful moment because they had promised to bring their brother back, yet events moved beyond their control.

The brothers tell their father that he can ask the people of the town and the caravan to verify their story. This time, they are trying to support their words with witnesses.

The pain is that their father’s trust has already been wounded before. Even truthful words can become hard to accept when past lies have broken confidence.

Ya‘qub, peace be upon him, responds with the same powerful phrase he used before: beautiful patience. His grief has returned, but his faith remains alive.

He does not only hope for one son. He hopes Allah will bring them all back. Even in deep pain, his heart trusts Allah’s knowledge and wisdom.

Ya‘qub’s grief becomes intense again. He remembers Yusuf, peace be upon him, and his eyes are affected by sorrow.

This ayah shows that deep faith does not mean a person feels no pain. Prophets felt sorrow, but they turned their pain toward Allah and did not rebel against Him.

The sons see their father’s grief and say that he will keep remembering Yusuf until his sorrow destroys him.

They do not fully understand the depth of his pain or the hope inside his heart. Sometimes people around grief only see sadness, while Allah knows the faith hidden within it.

Ya‘qub, peace be upon him, explains that he is not complaining against Allah. He is pouring his grief out to Allah.

This ayah is one of the most comforting lessons in the Quran: turning pain into dua is not weakness. It is worship. A believer may cry, but the heart knows where to take its sorrow.

Ya‘qub, peace be upon him, does not give up. Even after years of grief, he tells his sons to search for Yusuf and his brother.

This ayah teaches that hope in Allah must stay alive. Despair is not the path of believers. Even when the situation looks impossible, Allah’s relief can arrive from a direction no one expects.

The brothers return to Yusuf, now humbled by hardship. They admit that they and their family are in difficulty and that they have brought only poor-quality goods.

They ask for full measure and charity. The ones who once acted from pride and jealousy now stand in need before the brother they harmed.

Yusuf finally speaks in a way that points them back to their past. He asks if they understand what they did to Yusuf and his brother when they were acting in ignorance.

Notice the mercy in his wording. He does not explode with revenge. He describes their wrongdoing as ignorance, opening a door for recognition, shame, and repentance.

The brothers finally realize that the powerful man before them is Yusuf, the brother they once harmed. Yusuf reveals himself and immediately gives credit to Allah’s favour.

He summarizes the lesson of his whole journey: taqwa and patience are never wasted. Allah carried Yusuf from the well, through slavery and prison, to honour and reunion.

The brothers finally admit the truth. They recognize that Allah raised Yusuf, peace be upon him, above them and that they were wrong in what they did.

This is an important moment of repentance. They no longer defend their jealousy or hide behind excuses. They confess their mistake openly.

Yusuf, peace be upon him, forgives his brothers with extraordinary nobility. He does not humiliate them, list their crimes, or take revenge.

He points them toward Allah’s forgiveness. This is the beauty of a heart healed by taqwa: it can remember the pain without becoming a prisoner of revenge.

Yusuf sends his shirt to his father. Earlier, a shirt was used in a false story of loss. Now, a shirt becomes the sign of truth, healing, and reunion.

He also asks them to bring the whole family to Egypt. The story is moving from separation toward restoration.

Before the shirt reaches him, Ya‘qub, peace be upon him, senses the scent of Yusuf. His hope was not dead. Allah allows his heart to feel that relief is near.

This ayah shows how Allah can send signs of relief before the relief fully arrives. What others may dismiss can be real comfort from Allah.

Those around Ya‘qub dismiss his hope and think he is still lost in old grief over Yusuf. They cannot yet see what Allah is about to reveal.

This ayah teaches that people may misunderstand hope when they do not know what Allah has placed in the heart of His servant.

The shirt reaches Ya‘qub, peace be upon him, and Allah restores his sight. The grief that affected his eyes is now met with a miracle of relief.

Ya‘qub reminds them that his hope was not empty. He knew from Allah what they did not know. The hidden plan is now becoming visible.

The brothers now ask their father to seek forgiveness for them. Their confession becomes clearer and more humble.

They had hurt Yusuf and Ya‘qub deeply. Now they recognize that their action was not merely a family mistake, but a sin needing forgiveness from Allah.

Ya‘qub, peace be upon him, responds with mercy and promises to ask Allah to forgive them. He points them toward Allah’s names: the Most Forgiving, the Most Merciful.

This ayah teaches that family healing needs both honesty and dua. The wrong must be admitted, but hope in Allah’s forgiveness must also remain open.
