'Umar bin Abu Salamah (May Allah be pleased with them) reported:
I was a boy under the care of Messenger of Allah (ﷺ), and as my hand used to wander around in the dish, he (ﷺ) said to me once, "Mention Allah's Name (i.e., say Bismillah), eat with your right hand, and eat from what is in front of you."[Al-Bukhari and Muslim].
