Perform religious acts with pure intentions and not just for show or to impress other people .

In this hadith, the Prophet Muhammad (PBUH) warns his followers about the dangers of hidden polytheism. This is when a person performs religious acts such as prayer or fasting in order to be seen by others and gain praise from them instead of doing it for Allah alone. The Prophet Muhammad (PBUH) was concerned that this kind of behavior could lead people away from true faith and piety and into a state where they are only performing religious acts for show or out of pride rather than sincerity. He wanted to remind his followers that their actions should always be done with pure intentions and not just for show or to impress other people.
