Narrated Abu Bakrah (may Allah be pleased with him): I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "When two Muslims meet each other with their swords (i.e., fight), both the killer and the one killed are in Hellfire." I said, "O Messenger of Allah! (It is understandable) for the killer, but what about the one who is killed?" He (peace and blessings of Allah be upon him) said: "(It is because) he was eager to kill his companion."
