Sayyiduna Anas (may Allah be pleased with him) said: Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) came to the Messenger of Allah (peace and blessings be upon him) with traces of yellow (perfume) on him. When the Messenger of Allah (peace and blessings be upon him) asked, he told him: I have married a woman of the Ansar. He (peace and blessings be upon him) asked: "How much dower (mahr) did you give?" He said: Gold equal to the weight of a date-stone. The Messenger of Allah (peace and blessings be upon him) said: "Give a wedding feast (walimah), even if only with one goat."
