Lick one's fingers after eating or give it to someone else

The Prophet Muhammad (peace be upon him) taught us that after we finish eating, we should not wipe our fingers until we have licked them ourselves or given them to someone else to lick for us. This is a way of keeping our hands clean and hygienic. It is important for us to keep our hands clean so that germs and bacteria do not spread from person to person. We can also show respect for the food by licking our fingers as a sign of appreciation for the meal. This hadith teaches us about the importance of hygiene and respect for food.
