Focus on improving oneself before pointing out the flaws in others. Be kind and compassionate towards one another.

This hadith warns us against criticizing other Muslims. It was narrated by Muawiyah who heard the Prophet Muhammad say that if you find faults with Muslims, you will corrupt them. This means that when we criticize others, we are not only damaging their reputation but also leading them down a path of destruction. We should instead focus on our own faults and strive to improve ourselves before pointing out the flaws in others. Furthermore, this hadith teaches us to be kind and compassionate towards one another as criticism can have a negative impact on our relationships with each other.
