The Book of Good Manners
Excellence of Using the Right Hand for Performing Various Good Acts
وَعَن حَفصةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، كَانَ يَجْعَلُ يَمِينَهُ لِطَعَامِهِ وَشَرَابِهِ وَثِيَابِهِ، وَيَجْعَلُ يساره لما سِوَى ذَلِكَ. ((رَوَاهُ أَبُو دَاوُد وَالتِّرْمِذِيّ وغيره)).
Hafsah (May Allah be pleased with her) reported: Messenger of Allah (ﷺ) used to use his right hand for eating, drinking and wearing his clothes and used to use his left hand for other purposes. [Abu Dawud and At-Tirmidhi].
