It is narrated from a female companion (may Allah be pleased with her) that once the Noble Prophet (peace and blessings be upon him) came to my place and I was eating with my left hand. I was a poor woman. The Noble Prophet (peace and blessings 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.
