It was narrated from Abu Musa that the Messenger of Allah (ﷺ) said: “When two Muslims confront one another with their swords, both the killer and the slain will be in Hell.” They said: “O Messenger of Allah, (we understand about) this killer, but what is wrong with the one who is slain?” He said: “He wanted to kill his companion.’”
