It was narrated from Anas bin Malik:the Prophet saw traces of yellow perfume on 'Abdur-Rahmaan bin 'Awf, and he asked him “What is this?” He said: “O Messenger of Allah, I married a women for the weight of a Nawah (Stone) of gold. He said: “May Allah bless you. Give a feast even if it is only with one sheep.”
حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا ثَابِتٌ الْبُنَانِيُّ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ رَأَى عَلَى عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ أَثَرَ صُفْرَةٍ فَقَالَ " مَا هَذَا أَوْ مَهْ " . فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي تَزَوَّجْتُ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ مِنْ ذَهَبٍ . فَقَالَ " بَارَكَ اللَّهُ لَكَ أَوْلِمْ وَلَوْ بِشَاةٍ " .
