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].
وعن حفصة رضي الله عنها أن رسول الله ﷺ ، كان يجعل يمينه لطعامه وشرابه وثيابه، ويجعل يساره لما سوى ذلك. ((رواه أبو داود والترمذي وغيره)).
