It is narrated from Hazrat Abu Musa (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When two Muslims come face to face with swords drawn and one of them kills the other, then both the killer and the killed will go to Hell. Someone asked, "O Messenger of Allah! (peace and blessings be upon him) The matter of the killer is understandable, but what about the killed one?" The Noble Prophet (peace and blessings be upon him) said: He also intended to kill his companion.
