Sahih Muslim 1069
Sahih Muslim · Book 12: The Book of Zakat · Zakat is forbidden for the messenger of Allah pbuh and his family, and they are Banu Hashim and Banu Al-Muttalib, and no one else
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، ح وَحَدَّثَنَا ابْنُ الْمُثَنَّى ، حَدَّثَنَا ابْنُ، أَبِي عَدِيٍّ كِلاَهُمَا عَنْ شُعْبَةَ ، فِي هَذَا الإِسْنَادِ كَمَا قَالَ ابْنُ مُعَاذٍ " أَنَّا لاَ، نَأْكُلُ الصَّدَقَةَ " .
This very hadith has been narrated on the authority of Sbu'ba with the same chain of transmitters.
