Practice cleanliness and hygiene; wash your hands before eating or handling food items; wash vessels after being licked by a dog seven times with dust as the first time.

This hadith teaches us about the importance of cleanliness and hygiene. The Prophet Muhammad (peace be upon him) taught us that if a dog licks any vessel, it should be washed seven times with dust as the first time. This is to ensure that all germs and bacteria are removed from the vessel before using it again. It is important to practice this in order to maintain good health and hygiene for ourselves and our families. We must also remember to always wash our hands before eating or handling food items, as this will help prevent any illnesses or diseases from spreading.
