Sahih Muslim 1427e
Abd al-Rahman b. 'Auf (Allah be pleased with him) reported that Messenger of Allah ﷺ saw the signs of the happiness of wedding in me, and I said: I have married a woman of the Ansar. He said: How much Mahr have you paid? I said: For a date-stone weight of gold. And in the hadith transmitted by Ishaq (it is): (nawat weight) of gold.
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَمُحَمَّدُ بْنُ قُدَامَةَ، قَالاَ أَخْبَرَنَا النَّضْرُ بْنُ شُمَيْلٍ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ صُهَيْبٍ، قَالَ سَمِعْتُ أَنَسًا، يَقُولُ قَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ رَآنِي رَسُولُ اللَّهِ ﷺ وَعَلَىَّ بَشَاشَةُ الْعُرْسِ فَقُلْتُ تَزَوَّجْتُ امْرَأَةً مِنَ الأَنْصَارِ . فَقَالَ " كَمْ أَصْدَقْتَهَا " . فَقُلْتُ نَوَاةً . وَفِي حَدِيثِ إِسْحَاقَ مِنْ ذَهَبٍ .
