The Qur'an does not give details of Isaac's life , but reliable Qur'anic commentators mentioned that when Abraham felt that his life was drawing to a close, he wished to see Issac married. He did not want Isaac to marry one of the Canaanites, who were pagans, so he sent a trustworthy servant to Haran in Iraq to choose a bride for Isaac. The servant's choice fell on Rebekah Bint Bethuel, Ibn Nahor, who was a brother of Abraham. Isaac married her and she gave birth to a set of twins, Esau (Al-Eis) and Jacob (Yaqub).
Ill feelings developed between the two brothers when they grew into manhood. Esau disliked the fact that Jacob was favored by his father and by Allah with prophethood. This ill-feeling became so serious that Esau threatened to kill his brother. Fearing for his life, Jacob fled the country.
