Narrated Anas: When `Abdur-Rahman bin `Auf came to us, Allah's Apostle made a bond of fraternity between him and Sa`d bin Ar-Rabi` who was a rich man, Sa`d said, The Ansar know that I am the richest of all of them, so I will divide my property into two parts between me and you, and I have two wives; see which of the two you like so that I may divorce her and you can marry her after she becomes lawful to you by her passing the prescribed period (i.e. 'Idda) of divorce. `Abdur Rahman said, May Allah bless you your family (i.e. wives) for you. (But `Abdur-Rahman went to the market) and did not return on that day except with some gain of dried yogurt and butter. He went on trading just a few days till he came to Allah's Apostle bearing the traces of yellow scent over his clothes. Allah's Apostle asked him, What is this scent? He replied, I have married a woman from the Ansar. Allah's Apostle asked, How much Mahr have you given? He said, A date-stone weight of gold or a golden date-stone. The Prophet said, Arrange a marriage banquet even with a sheep.
