Sayyiduna Anas bin Malik (may Allah be pleased with him) said: Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him), wearing a yellow garment. The Prophet (peace and blessings be upon him) asked him: "Mahyam?" (The narrator said:) This is a word used when asking about something. He said: O Messenger of Allah! I have got married. The Prophet (peace and blessings be upon him) asked: "For how much (dowry)?" He said: For gold equal to the weight of a date stone. The Prophet (peace and blessings be upon him) said: "Hold a walimah, even if it is with one goat (slaughtered for the feast)." Sayyiduna Anas (may Allah be pleased with him) said: We estimated it at a quarter of a dinar. (Allamah al-Haythami says:) I say: This report is mentioned in the Sahih, but without the mention of the value of the date stone.
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, al-Qasim bin Ma'n, and I have not found anyone who has written his biography.
