Maintain cleanliness and strive for honesty in all dealings with others.

This hadith is narrated by Abu Razin, who saw Abu Hurairah hitting his forehead with his hand and saying that he would never lie against the Messenger of Allah. The Prophet then said that if a dog licks a vessel, it should be washed seven times in order to maintain cleanliness. This hadith teaches us about the importance of cleanliness as well as honesty. It emphasizes that we should always strive to be honest in our dealings with others, even if it may not be convenient for us or may cause us harm. We must also take care to ensure that our vessels are kept clean at all times, even if a dog has licked them.
