'Umar bin Abu Salamah (May Allah be pleased with him) reported:
I was a boy under the care of Messenger of Allah ﷺ, and my hand would wander about in the dish. Messenger of Allah ﷺ said to me "Mention Allah's Name (i.e., say Bismillah before you start eating), eat with your right hand and eat from what is near to you". I always followed this way of eating after this incident.

[Al-Bukhari and Muslim].

وعن أبي حفص عمر بن أبي سلمة عبد الله بن عبد الأسد ربيب رسول الله ﷺ قال: كنت غلامًا في حجر رسول الله ﷺ وكانت يدي تطيش في الصحفة، فقال لي رسول الله ﷺ : " يا غلام سَمِّ الله تعالى، وكُل بيمينك، وكُل مما يليك" فما زالت تلك طعمتي بعد. ((متفق عليه)).
