Sunan an-Nasai
أَخْبَرَنَا عَمْرُو بْنُ يَزِيدَ، قَالَ حَدَّثَنَا بَهْزُ بْنُ أَسَدٍ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ عَمْرُو بْنُ مُرَّةَ أَخْبَرَنِي قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ أَبِي أَوْفَى، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا أَتَاهُ قَوْمٌ بِصَدَقَتِهِمْ قَالَ " اللَّهُمَّ صَلِّ عَلَى آلِ فُلاَنٍ " . فَأَتَاهُ أَبِي بِصَدَقَتِهِ فَقَالَ " اللَّهُمَّ صَلِّ عَلَى آلِ أَبِي أَوْفَى " .
It was narrated that 'Abdullah bin Abi Awfa said: "When people brought their Zakah to him, the Messenger of Allah would say: 'O Allah, send salah upon the family of so-and-so,' My father brought his Sadaqah to him and he said: 'O Allah, send Salah upon the family of Abu Awfa."'
