Narrated Ibn Abi `Aufa:
حَدَّثَنَا مُسْلِمٌ ، حَدَّثَنَا شُعْبَةُ ، عَنْ عَمْرٍو ، سَمِعْتُ ابْنَ أَبِي أَوْفَى ـ رضى الله عنهما كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أَتَاهُ رَجُلٌ بِصَدَقَةٍ قَالَ " اللَّهُمَّ صَلِّ عَلَى آلِ فُلاَنٍ ". فَأَتَاهُ أَبِي فَقَالَ " اللَّهُمَّ صَلِّ عَلَى آلِ أَبِي أَوْفَى " .
Whenever a man brought his alms to the Prophet, the Prophet (ﷺ) would say, "O Allah! Bestow Your Blessing upon the family of so-and-so." When my father came to him (with his alms), he said, "O Allah! Bestow Your Blessings upon the family of Abi `Aufa."
