Sahih Muslim , Book 8, Hadith 3323 (USC-MSA) ⓘ
Abd al-Rahman b. 'Auf (Allah be pleased with him) reported that Allah's Messenger 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 صلى الله عليه وسلم وَعَلَىَّ بَشَاشَةُ الْعُرْسِ فَقُلْتُ تَزَوَّجْتُ امْرَأَةً مِنَ الأَنْصَارِ . فَقَالَ " كَمْ أَصْدَقْتَهَا " . فَقُلْتُ نَوَاةً . وَفِي حَدِيثِ إِسْحَاقَ مِنْ ذَهَبٍ .
