The Prophet’s guidance with regard to food is perfect guidance. It was described by Ibn al-Qayyim as follows:
When he put his hand in the food, he would say, “Bismillaah (in the Name of Allaah), and he told people to say this when eating. He said, “When any one of you eats, let him mention the name of Allaah. If he forgets to mention the name of Allaah at the beginning, let him say Bismillaahi fi awwalihi wa aakhirihi (in the name of Allaah at its beginning and at its end).” Saheeh hadeeth, narrated by al-Tirmidhi (1859) and Abu Dawood (3767).
