Narrated Anas:
The Prophet (ﷺ) seeing a yellow mark (of perfume) on the clothes of `Abdur-Rahman bin `Auf, said, "What about you?" `Abdur-Rahman replied, "I have married a woman with a Mahr of gold equal to a date-stone." The Prophet (ﷺ) said, "May Allah bestow His Blessing on you (in your marriage). Give a wedding banquet, (Walima) even with one sheep."

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ رَأَى النَّبِيُّ صلى الله عليه وسلم عَلَى عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ أَثَرَ صُفْرَةٍ فَقَالَ " مَهْيَمْ ". أَوْ " مَهْ ". قَالَ تَزَوَّجْتُ امْرَأَةً عَلَى وَزْنِ نَوَاةٍ مِنْ ذَهَبٍ. فَقَالَ " بَارَكَ اللَّهُ لَكَ أَوْلِمْ وَلَوْ بِشَاةٍ ".
