Sahih al-Bukhari, Book 24, Hadith 98 (In-Book) ⓘ
Narrated 'Abdullah bin Abu Aufa : Whenever a person came to the Prophet with his alms, the Prophet would say, "O Allah! Send your Blessings upon so and so." My father went to the Prophet with his alms and the Prophet said, "O Allah! Send your blessings upon the offspring of Abu Aufa."
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرٍو، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أَتَاهُ قَوْمٌ بِصَدَقَتِهِمْ قَالَ " اللَّهُمَّ صَلِّ عَلَى آلِ فُلاَنٍ ". فَأَتَاهُ أَبِي بِصَدَقَتِهِ، فَقَالَ " اللَّهُمَّ صَلِّ عَلَى آلِ أَبِي أَوْفَى ".
