Sahih al-Bukhari 5167
Narrated Anas:
When `Abdur-Rahman bin `Auf married an Ansari woman, the Prophet (ﷺ) asked him, "How much Mahr 
did you give her?" `Abdur-Rahman said, "Gold equal to the weight of a date stone." Anas added: 
When they (i.e. the Prophet (ﷺ) and his companions) arrived at Medina, the emigrants stayed at the 
Ansar's houses. `Abdur-Rahman bin `Auf stayed at Sa`d bin Ar-Rabi's house. Sa`d said to `Abdur- 
Rahman, "I will divide and share my property with you and will give one of my two wives to you." 
`Abdur-Rahman said, "May Allah bless you, your wives and property (I am not in need of that; but 
kindly show me the way to the market)." So `Abdur-Rahman went to the market and traded there 
gaining a profit of some dried yoghurt and butter, and married (an Ansari woman). The Prophet (ﷺ) said 
to him, "Give a banquet, even if with one sheep."
حَدَّثَنَا عَلِيٌّ، حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنِي حُمَيْدٌ، أَنَّهُ سَمِعَ أَنَسًا ـ رضى الله عنه ـ قَالَ سَأَلَ النَّبِيُّ صلى الله عليه وسلم عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ وَتَزَوَّجَ امْرَأَةً مِنَ الأَنْصَارِ ‏"‏ كَمْ أَصْدَقْتَهَا ‏"‏‏.‏ قَالَ وَزْنَ نَوَاةٍ مِنْ ذَهَبٍ‏.‏ وَعَنْ حُمَيْدٍ سَمِعْتُ أَنَسًا قَالَ لَمَّا قَدِمُوا الْمَدِينَةَ نَزَلَ الْمُهَاجِرُونَ عَلَى الأَنْصَارِ فَنَزَلَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ عَلَى سَعْدِ بْنِ الرَّبِيعِ فَقَالَ أُقَاسِمُكَ مَالِي وَأَنْزِلُ لَكَ عَنْ إِحْدَى امْرَأَتَىَّ‏.‏ قَالَ بَارَكَ اللَّهُ لَكَ فِي أَهْلِكَ وَمَالِكَ‏.‏ فَخَرَجَ إِلَى السُّوقِ فَبَاعَ وَاشْتَرَى فَأَصَابَ شَيْئًا مِنْ أَقِطٍ وَسَمْنٍ فَتَزَوَّجَ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ أَوْلِمْ وَلَوْ بِشَاةٍ ‏"‏‏.‏
