Hasan narrates that Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) had a brother who used to take an active part in the tribulations. He would forbid him, but he would not desist. One day, Sayyiduna Abu Musa (may Allah be pleased with him) said to him: I used to think that a little admonition and advice from me would be sufficient for you, but the situation is that I am seeing the opposite. The Messenger of Allah (peace and blessings be upon him) said: When two Muslims come out against each other with their swords and one of them kills the other, then both the killer and the killed will be in Hell. The Companions asked: O Messenger of Allah! The killer is in Hell, but what is the reason for the killed being in Hell? He (peace and blessings be upon him) said: He had intended to kill his opponent.
