It was narrated that Ibn Juraij said: ‘Ata’ told me that he heard Ibn 'Abbas (رضي الله عنه) say: The Messenger of Allah (ﷺ) said:

“When one of you eats food, let him not wipe his hand until he has licked it or had it licked for him.“ Abuz-Zubair said: I heard Jabir bin 'Abdullah say that: I heard it from the Prophet (ﷺ): "Let the meal not be cleared away until he licks it (his hand) or has it licked for him, for the last of the food is where the barakah (blessing) is.”
