Be honest with everyone

This hadith warns us against being double-faced, which means presenting one face to some people and another face to others. This is considered a bad trait because it shows that the person does not have integrity or honesty. Instead of being honest with everyone, they are trying to manipulate the situation by presenting different faces depending on who they are talking to. This kind of behavior can lead people astray and cause confusion in society as it is difficult for others to know what the person's true intentions are. Therefore, this hadith encourages us all to be honest and consistent in our dealings with others so that we can maintain trustworthiness and integrity in our relationships.
