Sahih al-Bukhari 3781

Narrated Anas:

When `Abdur-Rahman bin `Auf came to us, Allah’s Messenger (ﷺ) 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 Messenger (ﷺ) bearing the traces of yellow scent over his clothes. Allah’s Messenger (ﷺ)
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 (ﷺ) said, “Arrange a marriage banquet even with a sheep.”
