The Book of Zakat
12/50. Chapter:
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
Sahih Muslim
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَزُهَيْرُ بْنُ حَرْبٍ جَمِيعًا عَنْ وَكِيعٍ، عَنْ شُعْبَةَ، بِهَذَا الإِسْنَادِ وَقَالَ " أَنَّا لاَ، تَحِلُّ لَنَا الصَّدَقَةُ " .
This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters (and the words of the Holy Prophet) are: " Sadaqa is not permissible for us."
