Iyas bin Salamah bin Akwa’ narrates from his father: A man was sitting with the Prophet (peace be upon him) and was eating with his left hand. The Prophet (peace be upon him) said to him: Eat with your right hand. He replied: I cannot do that. The Prophet (peace be upon him) said: You will not be able to do it. After that, the man was never able to raise his (right hand) to his mouth.
