According to search-discovered classical Islamic scholarship, Prophet Yaqub (يعقوب), also known as Isra'il, is a revered prophet in Islam, the son of Prophet Ishaq and grandson of Prophet Ibrahim. He is mentioned sixteen times in the Quran and is esteemed as a man of great faith, wisdom, and strength who steadfastly preached monotheism. His life, particularly as detailed in Surah Yusuf, is the epitome of 'Sabrun Jameel' (beautiful patience), demonstrating profound trust in Allah's plan despite enduring the prolonged separation from his beloved son, Yusuf, a grief so intense it caused him temporary blindness. As the father of twelve sons who would lead the twelve tribes of Israel (Bani Israel), his legacy is central to prophetic history. Classical commentators like Ibn Kathir highlight his final testament, where he gathered his sons to ensure they would worship the One God after his death, cementing his role as a patriarch who secured the continuation of the monotheistic faith of his forefathers.
