Sahl bin Sa'd As-Sa'idi narrated that:A woman came to the Messenger of Allah and said: ""I present myself to you (for marriage)."" So she stood for a long time. Then a man said: ""O Messenger of Allah! Marry her to me if you have no need of her."" So he said: ""Do you have anything to give her as a dowry?"" He said: ""I have nothing except this Izar.""

He said: ""Search for something, even if it just an iron ring."" He said: So he searched but he did not find anything. The Messenger of Allah said: ""Do you have any Qur'an (memorized)?"" He said: ""Yes. This Surat and that Surat."" And he named the Surat. So the Messenger of Allah said: ""I marry her to you for what you have (memorized) of the Qur'an
