(109) Chapter: Excellence of Eating with Three Fingers and Licking Them

Ka'b bin Malik (May Allah be pleased with him) reported:
I saw Messenger of Allah (ﷺ) eating with three fingers (i.e., the thumb, the index finger and the middle finger) and licking them after having finished the food.

[Muslim].

Commentary: To use less than three fingers for eating speaks of the manner of the arrogant, whereas to use both hands to this end is indicative of an overpowering greed. So, the best way of eating is that shown by Messenger of Allah (PBUH). Here, too, is the affirmation of licking the fingers after taking meal, and not during it.
