باب غَزْوَةِ الْحُدَيْبِيَةِ
Sahih al-Bukhari 4166

Narrated `Abdullah bin Abi `Aufa:

(Who was one of those who had given the Pledge of allegiance to the Prophet (ﷺ) beneath the Tree) When the people brought Sadaqa (i.e. rak`at) to the Prophet (ﷺ) he used to say, "O Allah! Bless them with your Mercy." Once my father came with his Sadaqa to him whereupon he (i.e. the Prophet) said. "O Allah! Bless the family of Abu `Aufa."

حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرِو بْنِ مُرَّةَ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ أَبِي أَوْفَى ـ وَكَانَ مِنْ أَصْحَابِ الشَّجَرَةِ ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أَتَاهُ قَوْمٌ بِصَدَقَةٍ قَالَ ‏"‏ اللَّهُمَّ صَلِّ عَلَيْهِمْ ‏"‏‏.‏ فَأَتَاهُ أَبِي بِصَدَقَتِهِ فَقَالَ ‏"‏ اللَّهُمَّ صَلِّ عَلَى آلِ أَبِي أَوْفَى ‏"‏‏.‏
