Sahl bin Sa'd said:
I was among the people with the Prophet when a woman stood up and said: 'O Messenger of Allah, she has offered herself in marriage to you, so see what you think of her.' He remained silent and the Prophet did not give any answer. Then she stood up (again) and said: 'O Messenger of Allah, she has offered herself in marriage to you, so see what you think of her.' A man stood up and said: 'Marry her to me, O Messenger of Allah!' He said: 'Do you have anything?' He said: 'No.' He said: 'Go and look, even if it is just an iron ring.' So he went and looked then he came and said: 'I could not find anything, not even an iron ring.' He said: 'Have you memorized anything of the Qur'an?' He said: 'Yes, Surah such-and-such and Surah such-and-such.' He said: 'I will marry you to her on the basis of what you have memorized of the Qur'an.'
