How much do you memorize from Qur'an? He said: Surat al-Baqarah or the one that follows it. He said: Stand up and teach her twenty verses: she is your wife.
Sunan Abi Dawud Book 12, Hadith 67
← Previous Hadith A woman came to the Messenger of Allah (ﷺ) and said: Messenger of Allah, I have offered myself to you. When she stood for a long time, a man got up and said: Messenger of Allah, marry her to me if you have no need for her. The Messenger of Allah (ﷺ) asked: Have you anything to give her as dower ? He replied: I have nothing by this lower garment of mine. The Messenger of Allah (ﷺ) said: If you give your lower garment, you will sit while you have no lower garment. So look for something else. He said: I do not find anything. He said: Look for something, even though it should be an iron ring. The man sought it but found nothing. The Messenger of Allah (ﷺ) said: Do you know anything from the Qur'an ? He said: Yes, I know surah so and so, which he named. The Messenger of Allah (ﷺ) said: I have given you her in marriage for the part of the Qur'an which you know.
