Ismail (Ishmael) - Tidings of Isaac - Qur'anic
Almighty Allah revealed: And verily, there came Our Messengers to Abraham with glad tidings. They said: "Salaam (greetings or peace)!" He answered: "Salaam (greetings or peace)" and he hastened to entertain them with a roasted calf. But when he saw their hands went not towards it (the meal), he felt some mistrust of them, and conceived a fear of them. They said: "Fear not, we have been sent against the people of Lot." And his wife was standing (there), and she laughed (either, because the Messengers did not eat their food or for being glad for the destruction of the people of Lot). But We gave her glad tidings of Isaac, and after him, of Jacob.
She said (in astonishment): "Woe unto me! Shall I bear a child while I am an old woman, and here is my husband, an old man? Verily! This is a strange thing!" They said: "Do you wonder at the Decree of Allah? The Mercy of Allah and His Blessings be on you, 0 the family (of Abraham). Surely, He (Allah) is All-Praiseworthy, All-Glorious." Surah 11: 69-73
