Umar bin Abu Salama reported,

I was a young boy under the care of the Messenger of Allah ﷺ, and my hand used to wander about in the dish. The Messenger of Allah ﷺ said to me, "Young man, mention the name of Allah, eat with your right hand, and eat from what is in front of you." That has been my way of eating ever since.
