It is narrated from a female companion (may Allah be pleased with her) that once the Prophet (peace be upon him) came to my place while I was eating with my left hand. I was a poor woman. The Prophet (peace be upon him) struck my hand, causing the morsel to fall, and said: When Allah has made your right hand, do not eat with your left hand. So I started eating with my right hand and after that, I never ate with my left hand again.
