The supplication for the one who brings Charity
Sahih Muslim
وَحَدَّثَنَاهُ ابْنُ نُمَيْرٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، عَنْ شُعْبَةَ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ " صَلِّ عَلَيْهِمْ " .
This hadith has been narrated by Shu'ba with the same chain of transmitters (but with a slight variation of words, that he said): (O Allah), bless them."
