Narrated Anas:

The Prophet 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 ﷺ 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 ".
