Sayyiduna Anas bin Malik (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) saw traces of yellow on Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) and said: "What is this?" He said: I have married a woman for gold equal to the weight of a date-stone. He (peace and blessings be upon him) said: "May Allah bless you. Give a wedding feast (walimah), even if with one goat."
(24) Chapter: It is recommended, if one has the means, to give the wedding feast with a goat.
