Sahih al-Bukhari, Book 80, Hadith 29 (In-Book) ⓘ

Narrated Ibn Abi `Aufa: Whenever a man brought his alms to the Prophet, the Prophet 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."

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 ‏"‏‏.‏
