Sunan Abi Dawud Book 28, Hadith 34
I do not eat while reclining.
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.
The Messenger of Allah (ﷺ) was never seen reclining while eating, nor walking with two men at his heels.
