Isaac is mentioned fifteen times by name in the Qur'an, often with his father and his son, Yaʿqūb. The Qur'an states that Abraham received "good tidings of Isaac, a prophet, of the righteous", and that God blessed them both (XXXVII: 12). 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" (XI: 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 (VI: 84; XIX: 49-50), and XXIX: 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 Qur'an, it later narrates that Abraham also praised God for giving him Ishmael and Isaac in his old age (XIV: 39-41).
Elsewhere in the Qur'an, Isaac is mentioned in lists: Joseph follows the religion of his forefathers Abraham, Isaac and Jacob (XII: 38) and speaks of God's favor to them (XII: 6); Yaʿqūb's sons all testify their faith and promise to worship the God that their forefathers, "Abraham, Ishmael and Isaac", worshiped (II: 127); and the Qur'an commands Muslims to believe in the revelations that were given to "Abraham, Ishmael, Isaac, Jacob and the Patriarchs" (II: 136; III: 84). In the Qur'an's narrative of Abraham's near-sacrifice of his son (XXXVII: 102), the name of the son is not mentioned and debate has continued over the son's identity, though many feel that the identity is the least important element in a story which is given to show the courage that one develops through faith.
Grave of Ishaq
His grave and that of his wife Rebekah is considered to be in the Cave of the Patriarchs in Hebron, known in Islam as the Ibrahim-i-Mosque ("Mosque of Abraham"). Alongside Isaac's grave are the graves of some of the other Qur'anic/Biblical patriarchs and their wives: Abraham and Sarah and Jacob and Leah.
