It was narrated that Ibn 'Abbas said:
"The Messenger of Allah never entrusted his purification to anyone nor his charity that he had given to anyone; he would be the one to take care of these matters himself."

حَدَّثَنَا أَبُو بَدْرٍ، عَبَّادُ بْنُ الْوَلِيدِ حَدَّثَنَا مُطَهَّرُ بْنُ الْهَيْثَمِ، حَدَّثَنَا عَلْقَمَةُ بْنُ أَبِي جَمْرَةَ الضُّبَعِيُّ، عَنْ أَبِيهِ أَبِي جَمْرَةَ الضُّبَعِيِّ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كَانَ رَسُولُ اللَّهِ ﷺ لاَ يَكِلُ طُهُورَهُ إِلَى أَحَدٍ وَلاَ صَدَقَتَهُ الَّتِي يَتَصَدَّقُ بِهَا يَكُونُ هُوَ الَّذِي يَتَوَلاَّهَا بِنَفْسِهِ .
