Sunan Abu Dawud 33
Purification (Kitab Al-Taharah)
حَدَّثَنَا أَبُو تَوْبَةَ الرَّبِيعُ بْنُ نَافِعٍ، حَدَّثَنِي عِيسَى بْنُ يُونُسَ، عَنِ ابْنِ أَبِي عَرُوبَةَ، عَنْ أَبِي مَعْشَرٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَائِشَةَ، قَالَتْ كَانَتْ يَدُ رَسُولِ اللَّهِ صلى الله عليه وسلم الْيُمْنَى لِطُهُورِهِ وَطَعَامِهِ وَكَانَتْ يَدُهُ الْيُسْرَى لِخَلاَئِهِ وَمَا كَانَ مِنْ أَذًى .
Narrated Aisha, Ummul Mu'minin: The Prophet (ﷺ) used his right hand for getting water for ablution and taking food, and his left hand for his evacuation and for anything repugnant
