Narrated Anas bin Malik:`Abdur-Rahman bin `Auf came to Allah's Messenger (ﷺ) and he had marks of Sufra (yellow perfume). Allah's Messenger (ﷺ) asked him (about those marks). `AbdurRahman bin `Auf told him that he had married a woman from the Ansar. The Prophet (ﷺ) asked, "How much Mahr did you pay her?" He said, "I paid gold equal to the weight of a date stone." Allah's Messenger (ﷺ) said to him, "Give a wedding banquet, even if with one sheep."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسِ بْنِ مَالِكٍ، رضى الله عنه أَنَّ عَبْدَ، الرَّحْمَنِ بْنَ عَوْفٍ جَاءَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَبِهِ أَثَرُ صُفْرَةٍ فَسَأَلَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَأَخْبَرَهُ أَنَّهُ تَزَوَّجَ امْرَأَةً مِنَ الأَنْصَارِ قَالَ " كَمْ سُقْتَ إِلَيْهَا ". قَالَ زِنَةَ نَوَاةٍ مِنْ ذَهَبٍ. قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَوْلِمْ وَلَوْ بِشَاةٍ ".
