ʿAbdur-Rahman bin ʿAuf came (from Mecca to Medina) and the Prophet ﷺ made a bond of brotherhood between him and Saʿd bin Ar-Rabiʿ Al-Ansari. Al-Ansari had two wives, so he suggested that ʿAbdur- Rahman take half, his wives and property. ʿAbdur-Rahman replied, "May Allah bless you with your wives and property. Kindly show me the market." So ʿAbdur-Rahman went to the market and gained (in bargains) some dried yoghurt and some butter. After a few days the Prophet ﷺ saw ʿAbdur-Rahman with some yellow stains on his clothes and asked him, "What is that, O ʿAbdur-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."
قَدِمَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ فَآخَى النَّبِيُّ ﷺ بَيْنَهُ وَبَيْنَ سَعْدِ بْنِ الرَّبِيعِ الأَنْصَارِيِّ وَعِنْدَ الأَنْصَارِيِّ امْرَأَتَانِ فَعَرَضَ عَلَيْهِ أَنْ يُنَاصِفَهُ أَهْلَهُ وَمَالَهُ فَقَالَ بَارَكَ اللَّهُ لَكَ فِي أَهْلِكَ وَمَالِكَ دُلُّونِي عَلَى السُّوقِ فَأَتَى السُّوقَ فَرَبِحَ شَيْئًا مِنْ أَقِطٍ وَشَيْئًا مِنْ سَمْنٍ فَرَآهُ النَّبِيُّ ﷺ بَعْدَ أَيَّامٍ وَعَلَيْهِ وَضَرٌ مِنْ صُفْرَةٍ فَقَالَ مَهْيَمْ يَا عَبْدَ الرَّحْمَنِ فَقَالَ تَزَوَّجْتُ أَنْصَارِيَّةً قَالَ فَمَا سُقْتَ قَالَ وَزْنَ نَوَاةٍ مِنْ ذَهَبٍ قَالَ أَوْلِمْ وَلَوْ بِشَاةٍ
