Narrated Anas:

Abdur Rahman bin 'Auf married a woman and gave her gold equal to the weight of a date stone (as Mahr). When the Prophet noticed the signs of cheerfulness of the marriage (on his face) and asked him about it, he said, "I have married a woman and gave (her) gold equal to a date stone in weight (as Mahr)."

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسٍ، أَنَّ عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ، تَزَوَّجَ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ، فَرَأَى النَّبِيُّ ﷺ بَشَاشَةَ الْعُرْسِ فَسَأَلَهُ فَقَالَ إِنِّي تَزَوَّجْتُ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ. وَعَنْ قَتَادَةَ عَنْ أَنَسٍ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ تَزَوَّجَ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ مِنْ ذَهَبٍ.
