Do not spy on or find faults with other Muslims unless their sin is overt; be kind to one another; try to help those who have done something wrong understand why what they did was wrong; avoid wrongdoing.

This hadith teaches us that we should not spy on or find faults with other Muslims unless their sin is overt. It is important to remember that Allah has prohibited us from spying and finding fault with others, as it can lead to a lot of harm and hurt feelings. We should only take action if the sin is obvious, so that we can help our fellow Muslim brothers and sisters stay away from wrongdoings. This hadith also teaches us the importance of being kind to one another, even when someone has done something wrong. Instead of judging them harshly, we should try to help them understand why what they did was wrong and how they can avoid doing it again in the future.
