Narrated Anas:

When Abdur-Rahman bin Auf came to Medina, the Prophet established a bond of brotherhood between him and Sad bin Ar-Rabi al-Ansari. Sad was a rich man, so he said to 'Abdur-Rahman, "I will give you half of my property and will help you marry." 'Abdur-Rahman said (to him), "May Allah bless you in your family and property. Show me the market." So 'Abdur-Rahman did not return from the market) till he gained some dried buttermilk (yoghurt) and butter (through trading). He brought that to his house-hold. We stayed for some-time (or as long as Allah wished), and then Abdur-Rahman 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 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."

حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ قَدِمَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ الْمَدِينَةَ فَآخَى النَّبِيُّ ﷺ بَيْنَهُ وَبَيْنَ سَعْدِ بْنِ الرَّبِيعِ الأَنْصَارِيِّ، وَكَانَ سَعْدٌ ذَا غِنًى، فَقَالَ لِعَبْدِ الرَّحْمَنِ أُقَاسِمُكَ مَالِي نِصْفَيْنِ، وَأُزَوِّجُكَ. قَالَ بَارَكَ اللَّهُ لَكَ فِي أَهْلِكَ وَمَالِكَ، دُلُّونِي عَلَى السُّوقِ. فَمَا رَجَعَ حَتَّى اسْتَفْضَلَ أَقِطًا وَسَمْنًا، فَأَتَى بِهِ أَهْلَ مَنْزِلِهِ، فَمَكَثْنَا يَسِيرًا ـ أَوْ مَا شَاءَ اللَّهُ ـ فَجَاءَ وَعَلَيْهِ وَضَرٌ مِنْ صُفْرَةٍ، فَقَالَ لَهُ النَّبِيُّ ﷺ " مَهْيَمْ ". قَالَ يَا رَسُولَ اللَّهِ تَزَوَّجْتُ امْرَأَةً مِنَ الأَنْصَارِ. قَالَ " مَا سُقْتَ إِلَيْهَا ". قَالَ نَوَاةً مِنْ ذَهَبٍ، أَوْ وَزْنَ نَوَاةٍ مِنْ ذَهَبٍ. قَالَ " أَوْلِمْ وَلَوْ بِشَاةٍ ".
