Narrated Anas:The Prophet (ﷺ) saw the traces of Sufra (yellow perfume) on `Abdur-Rahman bin `Auf and said, "What is this?" `Abdur-Rahman, said, "I have married a woman and have paid gold equal to the weight of a datestone (as her Mahr). The Prophet (ﷺ) said to him, "May Allah bless you: Offer a wedding banquet even with one sheep."
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادٌ ـ هُوَ ابْنُ زَيْدٍ ـ عَنْ ثَابِتٍ، عَنْ أَنَسٍ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم رَأَى عَلَى عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ أَثَرَ صُفْرَةٍ قَالَ " مَا هَذَا ". قَالَ إِنِّي تَزَوَّجْتُ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ مِنْ ذَهَبٍ. قَالَ " بَارَكَ اللَّهُ لَكَ، أَوْلِمْ وَلَوْ بِشَاةٍ ".
