صحيح البخاري

Narrated Anas bin Malik:

`Abdur-Rahman bin `Auf came (from Mecca to Medina) and the Prophet (ﷺ) made a bond of brotherhood between him and Sa`d bin Ar-Rabi` Al-Ansari. Al-Ansari had two wives, so he suggested that `Abdur- Rahman take half, his wives and property. `Abdur-Rahman replied, "May Allah bless you with your wives and property. Kindly show me the market." So `Abdur-Rahman went to the market and gained (in bargains) some dried yoghurt and some butter. After a few days the Prophet (ﷺ) saw `Abdur-Rahman with some yellow stains on his clothes and asked him, "What is that, O `Abdur-Rahman?" He replied, "I had married an Ansari woman." The Prophet (ﷺ) asked, "How much Mahr did you give her?" He replied, "The weight of one (date) stone of gold." The Prophet (ﷺ) said, "Offer a banquet, even with one sheep."
