Sunan Abi Dawud Book 28, Hadith 37
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 Prophet(ﷺ) sent me(for some work), and when I returned to him found him eating dates and squatting.
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
