Sunan Abi Dawud Book 28, Hadith 38
The Prophet (ﷺ) had a bowl called gharra'. It was carried by four persons. When the sun rose high, and they performed the forenoon prayer, the bowl in which tharid was prepared was brought, and the people gathered round it. When they were numerous, the Messenger of Allah (ﷺ) said: Allah has made me a respectable servant, and He did not make me an obstinate tyrant. The Messenger of Allah (ﷺ) said: Eat from it sides and leave its top, the blessing will be conferred on it
The Prophet (ﷺ) said: When one of you eats, he must not eat from the top of the dish, but should eat from the bottom; for the blessing descends from the top of it.
The Messenger of Allah (ﷺ) forbade two kinds of food: to sit at cloth on which wine is drunk, and to eat by a man while lying on his stomach.
Abu Dawud said : Ja'far did not hear this tradition from al-Zuhri. His tradition is rejected.
