(33) بَابُ هَلْ يُصَلَّى عَلَى غَيْرِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
Narrated Ibn Abi `Aufa:
Whenever somebody brought alms to the Prophet (ﷺ) the used to say, "Allahumma Salli 'Alaihi (O Allah! Send Your Salat (Grace and Honor) on him)." Once when my father brought his alms to him, he said, "O Allah! Send Your Salat (Grace and Honor) on the family of Abi `Aufa."
