Be honest in your words and actions .

The Prophet Muhammad (PBUH) warned us about the danger of hypocrisy, which is when someone pretends to have beliefs or values that they do not actually possess. He said that what he feared most for his followers, or ummah, was a hypocrite who speaks with knowledge. This means that someone who knows how to use words and arguments in order to deceive people can be very dangerous because they can manipulate others into believing something false or wrong. Therefore, it is important for us to be aware of this type of person and not trust them blindly without verifying their claims first. We should also strive to be honest in our own words and actions so as not to fall into hypocrisy ourselves.
