Narrated AbuRafi':

The Prophet (ﷺ) sent a man of the Banu Makhzum to collect sadaqah. He said to AbuRafi': Accompany me so that you may get some of it. He said: (I cannot take it) until I go to the Prophet (ﷺ) and ask him. Then he went to him and asked him. He said: The sadaqah is not lawful for us, and the client of a people is treated as one of them.

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنِ ابْنِ أَبِي رَافِعٍ، عَنْ أَبِي رَافِعٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم بَعَثَ رَجُلاً عَلَى الصَّدَقَةِ مِنْ بَنِي مَخْزُومٍ فَقَالَ لأَبِي رَافِعٍ اصْحَبْنِي فَإِنَّكَ تُصِيبُ مِنْهَا ‏.‏ قَالَ حَتَّى آتِيَ النَّبِيَّ صلى الله عليه وسلم فَأَسْأَلَهُ فَأَتَاهُ فَسَأَلَهُ فَقَالَ ‏

‏ مَوْلَى الْقَوْمِ مِنْ أَنْفُسِهِمْ وَإِنَّا لاَ تَحِلُّ لَنَا الصَّدَقَةُ ‏
