The family line through Ishaq عليه السلام
Through Ishaq عليه السلام came Ya‘qub عليه السلام. Ya‘qub عليه السلام is also known as Isra’il, and from him came the Children of Isra’il. Many prophets mentioned in the Qur’an came from this line, including Yusuf, Musa, Harun, Dawud, Sulayman, Zakariya, Yahya, and ‘Isa عليهم السلام.
This does not reduce the honour of Isma’il عليه السلام. Rather, it shows the two great blessed lines from Ibrahim عليه السلام: through Isma’il عليه السلام came the noble lineage of Prophet Muhammad ﷺ, and through Ishaq عليه السلام came Ya‘qub عليه السلام and many prophets of Bani Isra’il.
