صحيح بخاري

`Abdur Rahman bin `Auf said, "When we came to Medina as emigrants, Allah's Messenger (ﷺ) established a bond of brotherhood between me and Sa`d bin Ar-Rabi`. Sa`d bin Ar-Rabi` said (to me), 'I am the richest among the Ansar, so I will give you half of my wealth and you may look at my two wives and whichever of the two you may choose I will divorce her, and when she has completed the prescribed period (before marriage) you may marry her.' `Abdur-Rahman replied, "I am not in need of all that. Is there any marketplace where trade is practiced?' He replied, "The market of Qainuqa." `Abdur- Rahman went to that market the following day and brought some dried buttermilk (yogurt) and butter, and then he continued going there regularly. Few days later, `Abdur-Rahman came having traces of yellow (scent) on his body. Allah's Messenger (ﷺ) asked him whether he had got married. He replied in the affirmative. The Prophet (ﷺ) said, 'Whom have you married?' He replied, 'A woman from the Ansar.' Then the Prophet (ﷺ) asked, 'How much did you pay her?' He replied, '(I gave her) a gold piece equal in weigh to a date stone (or a date stone of gold)! The Prophet (ﷺ) said, 'Give a Walima (wedding banquet) even if with one sheep .' "
