Anas bin Malik reported,

Abdul-Rahman bin Awf came to us, and the Messenger of Allah ﷺ established a bond of brotherhood between him and Saad bin Rabi, who was a man of considerable wealth.Saad said, "The Ansar know that I am among the wealthiest of them. I will divide my wealth between us into two halves. I also have two wives, so look and see which of them pleases you more, and I will divorce her. Once her waiting period is complete, you may marry her."Abdul-Rahman replied, "May Allah bless you in your family and your wealth."He did not return that day until he had earned a profit of some clarified butter and dried curd. It was not long before he came to the Messenger of Allah ﷺ with traces of yellow perfume on him.The Messenger of Allah ﷺ asked him, "What is this?"He answered, "I have married a woman from the Ansar."The Prophet ﷺ asked, "What did you give her as a dowry?"He said, "The weight of a date-stone in gold," or, "a date-stone of gold."The Prophet ﷺ said, "Hold a wedding feast, even if only with a single sheep."

عن أنس رضي الله عنه أنه قال

قدم علينا عبد الرحمن بن عوف وآخى رسول الله ﷺ بينه وبين سعد بن الربيع وكان كثير المال فقال سعد قد علمت الأنصار أني من أكثرها مالا سأقسم مالي بيني وبينك شطرين ولي امرأتان فانظر أعجبهما إليك فأطلقها حتى إذا حلت تزوجتها فقال عبد الرحمن بارك الله لك في أهلك فلم يرجع يومئذ حتى أفضل شيئا من سمن وأقط فلم يلبث إلا يسيرا حتى جاء رسول الله ﷺ وعليه وضر من صفرة فقال له رسول الله ﷺ مهيم قال تزوجت امرأة من الأنصار فقال ما سقت إليها قال وزن نواة من ذهب أو نواة من ذهب فقال أولم ولو بشاة
