Hadith about Licking others fingers after eating?

Question

Assalamu Alaikum Brothers in Islam,

Regarding etiquettes of eating :

It was narrated from Ibn ‘Abbas that the Prophet (ﷺ) said: “When one of you eats food, let him not wipe his hand until he has licked it or has someone else to lick it.”(ibn Majah)

What does the part "or has someone else to lick it" mean? In what context can this be understood? How can it be lawful to lick another person's finger? Please clarify this.

Answer 1

Waalykom Alsalam Werahmato Allah ,

Licked by others who are not harmed by it; such as a small child, wife or husband . That there is a blessing in some parts of the food, and fear the Messenger of Allah peace be upon him to waste this blessing if the food remains in the fingers.
