The Messenger of Allah (ﷺ) said: When one of you eats, he should mention Allah's name; if he forgets to mention Allah's name at the beginning, he should say: "In the name of Allah at the beginning and at the end of it."
Sunan Abi Dawud Book 28, Hadith 32
← Previous Hadith The devil considers the food when Allah’s name is not mentioned over it, and he brought his nomad Arab that it might be lawful by means of him, so I seized his hand: then he brought this girl that it might be lawful by means of her, so I seized her hand. By Him in Whose hand my soul is, His hand is in my hand along with their hands.

Sunan Abi Dawud Book 28, Hadith 31 Next Hadith → Umayyah was sitting and a man was eating. He did not mention Allah's name until there remained the last morsel. When he raised it to his mouth, he said: In the name of Allah at the beginning and at the end of it. The Prophet (ﷺ) laughed and said: The devil kept eating along with him, but when he mentioned Allah's name, he vomited what was in his belly.

Abu Dawud: Jabir bin Subh is grandfather of Sulaiman bin Harb from his mother's side.
