حَدَّثَنَا يَحْيَى بْنُ يَحْيَى التَّمِيمِيُّ، وَأَبُو الرَّبِيعِ، سُلَيْمَانُ بْنُ دَاوُدَ الْعَتَكِيُّ وَقُتَيْبَةُ بْنُ سَعِيدٍ وَاللَّفْظُ لِيَحْيَى قَالَ يَحْيَى أَخْبَرَنَا وَقَالَ الآخَرَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم رَأَى عَلَى عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ أَثَرَ صُفْرَةٍ فَقَالَ " مَا هَذَا " . قَالَ يَا رَسُولَ اللَّهِ إِنِّي تَزَوَّجْتُ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ مِنْ ذَهَبٍ . قَالَ " فَبَارَكَ اللَّهُ لَكَ أَوْلِمْ وَلَوْ بِشَاةٍ ".
Anas b. Malik reported that Allah's Apostle (ﷺ) saw the trace of yellowness on 'Abd al-Rahman b. 'Auf and said: What is this? Thereupon he said: Allah's Messenger, I have married a woman for a date-stone's weight of gold. He said: God bless you! Hold a wedding feast, even if only with a sheep.
