When `Abdur-Rahman bin `Auf رضی اللہ عنہ came to Medina, the Prophet (ﷺ) established a bond of brotherhood between him and Sa`d bin Ar-Rabi al-Ansari رضی اللہ عنہ . Sa`d رضی اللہ عنہ was a rich man, so he said to `Abdur-Rahman رضی اللہ عنہ , "I will give you half of my property and will help you marry." `Abdur-Rahman رضی اللہ عنہ said (to him), "May Allah bless you in your family and property. Show me the market." So `Abdur-Rahman رضی اللہ عنہ did not return from the market) till he gained some dried buttermilk (yogurt) and butter (through trading). He brought that to his house-hold. We stayed for sometime (or as long as Allah wished), and then `Abdur-Rahman رضی اللہ عنہ came, scented with yellowish perfume. The Prophet (ﷺ) said (to him) "What is this?" He replied, "I got married to an Ansari woman." The Prophet (ﷺ) asked, "What did you pay her?" He replied, "A gold stone or gold equal to the weight of a date stone." The Prophet (ﷺ) said (to him), "Give a wedding banquet even if with one sheep."
