Hadith 2066
Abu al-Yaman said: My grandmother Umm Asim (may Allah have mercy on her) narrated that the freed slave of the Messenger of Allah (peace be upon him), Nubaisha, came to us while we were eating food. We invited him, and he began to eat with us. Then he said that the Messenger of Allah (peace be upon him) narrated to us: "Whoever eats from a large dish (or plate) and then licks it clean, that plate (or dish) will supplicate for his forgiveness."
