A man ate in the presence of Messenger of Allah (ﷺ) with his left hand. He (ﷺ) said, "Eat with your right hand." He said: "I cannot." Thereupon he (the Prophet (ﷺ)) said, "May you never be able to do that." It was arrogance that prevented him from doing it, and he could not raise it (the right hand) up to his mouth afterwards.
