Isaac is mentioned fifteen times by name in the Quran, often with his father and his son, Jacob (Yaʿqūb).[5] The Quran states that Abraham received "good tidings of Isaac, a prophet, of the righteous", and that God blessed them both (37: 112). "And We gave him glad tidings of Isaac, a prophet from among the righteous. And We blessed him and Isaac. And among their progeny are the virtuous and those who clearly wrong themselves"[6] In a fuller description, when angels came to Ibrahim to tell him of the future punishment to be imposed on Sodom and Gomorrah, his wife, Sarah, "laughed, and We gave her good tidings of Isaac, and after Isaac of (a grandson) Jacob" (11: 71–74); and it is further explained that this event will take place despite Abraham and Sarah's old age. Several verses speak of Isaac as a "gift" to Abraham (6: 84; 19: 49–50), and 29: 26-27 adds that God made "prophethood and the Book to be among his offspring", which has been interpreted to refer to Abraham's two prophetic sons, his prophetic grandson Jacob, and his prophetic great-grandson Joseph. In the Quran, it later narrates that Abraham also praised God for giving him Ishmael and Isaac in his old age (XIV: 39–41).
Elsewhere in the Quran, Isaac is mentioned in lists: Joseph follows the religion of his forefathers Abraham, Isaac and Jacob (12: 38) and speaks of God's favor to them (12: 6); Yaʿqūb's sons all testify their faith and promise to worship the God that their forefathers, "Abraham, Ishmael and Isaac", worshiped (2: 127); and the Quran commands Muslims to believe in the revelations that were given to "Abraham, Ishmael, Isaac, Jacob and the Patriarchs" (2: 136; III: 84).
