A woman came to the Prophet (peace and blessings be upon him) and offered herself (in marriage) to him. He (peace and blessings be upon him) said: "I have no need of women." A Companion (may Allah be pleased with him) said: O Messenger of Allah, give her to me in marriage. He (peace and blessings be upon him) said: "Do you have anything?" He said: No, I have nothing. He (peace and blessings be upon him) said: "Do you know any of the Qur'an?" He said: Yes, such-and-such surahs. He (peace and blessings be upon him) said: "I marry her to you on account of the Qur'an (that you know)."
