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
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ بْنُ هَمَّامٍ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ، مُنَبِّهٍ قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ مُحَمَّدٍ، رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " وَاللَّهِ إِنِّي لأَنْقَلِبُ إِلَى أَهْلِي فَأَجِدُ التَّمْرَةَ سَاقِطَةً عَلَى فِرَاشِي - أَوْ فِي بَيْتِي - فَأَرْفَعُهَا لآكُلَهَا ثُمَّ أَخْشَى أَنْ تَكُونَ صَدَقَةً - أَوْ مِنَ الصَّدَقَةِ - فَأُلْقِيهَا " .
Out of so many ahadith which Hammam b. Munabbih narrated on the authority of Abu Huraira from the Messenger of Allah (ﷺ) one is this that the Messenger of Allah (ﷺ) said: I go back to my family and I find a date lying on my bed or in my house, and I take it up to eat it, but then I throw it away fearing that it may be a Sadaqa or from Sadaqa.
