Try resolving differences peacefully without resorting to violence or aggression.

This hadith is narrated by Al-Ahnaf bin Qais and it talks about the consequences of two Muslims fighting each other with swords. According to this hadith, both the killer and the killed one will be in Hellfire. When Al-Ahnaf asked Allah's Messenger why this was so even for the killed one who was not at fault, he replied that it was because he was eager to kill his opponent. This hadith teaches us that we should not fight with our fellow Muslim brothers and sisters as it can lead to dire consequences for both parties involved. We should instead try to resolve our differences peacefully and without resorting to violence or aggression.
