أبو داود:٣٣حَدَّثَنَا 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 ﷺ الْيُمْنَى لِطُهُورِهِ وَطَعَامِهِ وَكَانَتْ يَدُهُ الْيُسْرَى لِخَلاَئِهِ وَمَا كَانَ مِنْ أَذًى
