Dhikr before Eating

`A’ishah narrated that the Messenger of Allah (peace be upon him) said: “When one of you eats food, then let him say: ‘Bismillah.’ If he forgets in the beginning, then let him say: ‘Bismillah Fi Awalihi Wa Akhirih (In the Name of Allah in its beginning and its end.)” (At-Tirmidhi)
