Mukhtasar Bukhari (Abridged) 1888 — Saying Bismillah and eating

It is narrated from Sayyiduna Umar bin Abu Salamah (may Allah be pleased with him) that I was a child and under the care of the Messenger of Allah (peace and blessings of Allah be upon him). At the time of eating, my hand would move around the dish, so the Messenger of Allah (peace and blessings of Allah be upon him) said to me: "O boy! Say Bismillah, eat with your right hand, and eat from what is in front of you." After that, this remained my way of eating always.
