Abdullah bin Abbas reported,

The Prophet ﷺ was brought a bowl of tharid and said, "Eat from its sides and do not eat from its center, for blessing descends in its center."In another wording, "When one of you eats food, let him not eat from the top of the dish, but let him eat from its lower part, for blessing descends from its top."

Sahih

عن ابن عباس

أن النبي ﷺ أتي بقصعة من ثريد فقال: كلوا من حولها، ولا تأكلوا من وسطها؛ فإن البركة تنزل في وسطها. وفي لفظ: إذا أكل أحدكم طعاما فلا يأكل من أعلى الصحفة، ولكن ليأكل من أسفلها، فإن البركة تنزل من أعلاها.
