Sahih Muslim 1078
Sahih Muslim · Book 12: The Book of Zakat · The supplication for the one who brings Charity
This hadith has been narrated by Shu'ba with the same chain of transmitters (but with a slight variation of words, that he said):
وَحَدَّثَنَاهُ ابْنُ نُمَيْرٍ ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ ، عَنْ شُعْبَةَ ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ " صَلِّ عَلَيْهِمْ " .
(O Allah), bless them."
