Sahih Muslim 5268
صحيح مسلم#5268SahihSalama b. Akwa' reported on the authority of his father that a person ate in the presence of Allah's Messenger (ﷺ) with his left hand, whereupon he said:Eat with your right hand. He said: I cannot do that, whereupon he (the Holy Prophet) said: May you not be able to do that. It was vanity that prevented him from doing it, and he could not raise it (the right hand) up to his mouth
