It was narrated from Sahl bin Sa'd that a woman came to the Messenger of Allah and said: "O Messenger of Allah, I give myself in marriage to you." She stood for a long time, then a man stood up and said: "Marry her to me if you do not want to marry her." The Messenger of Allah said: "Do you have anything?" He said: "I cannot find anything." He said: "Look (for something), even if it is only an iron ring." So he looked but he could not find anything. The Messenger of Allah said to him: "Have you (memorized) anything of the Qur'an?" He said: "Yes, Surah such and such and Surah such and such," naming them. The Messenger of Allah said: "I marry her to you for what you know of the Qur'an."
