Respect human life , Avoid violence , Maintain peace between fellow believers .

This hadith from Abu Musa Al-Ash'ari warns us about the consequences of killing another Muslim. It teaches us that if two Muslims confront each other with swords and one kills the other, they will both be punished in Hellfire. This hadith emphasizes that taking someone's life is a major sin and should not be taken lightly as it has serious consequences in this world and the hereafter. It also reminds us to stay away from any kind of violence or aggression towards our fellow believers, as it can lead to dire consequences for both parties involved. We should strive to maintain peace between ourselves and our fellow believers, even if we disagree on certain matters or have different opinions on certain topics.
