Mishkat al-Masabih 3513

Abu Hurayrah reported: A man came and said, ‘Messenger of God, what do you say if a man comes wanting to take my property?’ He said, ‘Do not give him your property.’ The man asked, ‘What if he fights me?’ He said, ‘Fight him.’ He asked, ‘What if he kills me?’ He said, ‘Then you are a martyr.’ He asked, ‘What if I kill him?’ He said, ‘He is in the Fire.’ Muslim transmitted it.
