Sunan Abi Dawud, Hadith 2104

Narrated Anas: The Messenger of Allah saw the trace of yellow on 'Abd al-Rahman b. 'Awf. The Prophet said: What is this ? He replied: Messenger of Allah, I have married a woman. He asked: How much dower did you give her ? He said: A nawat weight of gold. He said: Hold a wedding feast, even if only with a sheep.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ الْبُنَانِيِّ، وَحُمَيْدٍ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَأَى عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ وَعَلَيْهِ رَدْعُ زَعْفَرَانٍ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ مَهْيَمْ ‏"‏ ‏.‏ فَقَالَ يَا رَسُولَ اللَّهِ تَزَوَّجْتُ امْرَأَةً ‏.‏ قَالَ ‏"‏ مَا أَصْدَقْتَهَا ‏"‏ ‏.‏ قَالَ وَزْنَ نَوَاةٍ مِنْ ذَهَبٍ ‏.‏ قَالَ ‏"‏ أَوْلِمْ وَلَوْ بِشَاةٍ ‏"‏ ‏.‏
