وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا وَكِيعٌ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، وَحُمَيْدٍ، عَنْ أَنَسٍ، أَنَّ عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ، تَزَوَّجَ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ مِنْ ذَهَبٍ وَأَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ لَهُ " أَوْلِمْ وَلَوْ بِشَاةٍ " .
Anas b. Malik (Allah be pleased with him) reported that 'Abd al-Rahman b. 'Auf (Allah be pleased with him) married a woman for a date-stone's weight of gold and Allah's Apostle (ﷺ) said to him: Hold a wedding feast, even if only with a sheep.
