A man came to the Messenger of Allah (may Allah's peace and blessings be upon him) and said: O Messenger of Allah, what if a man comes to me wanting to take my money? He said: "Then do not give him your money." The man said: What if he fights with me? He said: "Then fight with him." The man said: What if he kills me? He said: "Then, you would be a martyr." The man said: What if I kill him? He said: "He would be in Hellfire."
