Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him): A man came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! If someone wants to take my wealth unjustly, what should I do? The Prophet (peace and blessings be upon him) said: Ask him by Allah (to desist). He said: If he does not accept? The Prophet (peace and blessings be upon him) said: Then ask him by Allah (again). He said: If he still does not accept? The Prophet (peace and blessings be upon him) said: For the third time, ask him by Allah. He said: If he still does not accept? The Prophet (peace and blessings be upon him) said: Then fight him, and if you are killed in that fight, you will go to Paradise, and if he is killed, he will go to Hell.

It is narrated from Sayyiduna Makharik (may Allah be pleased with him) that a man came to the Noble Prophet (peace and blessings be upon him) and said: "A man comes to me and wants to take my wealth." The Prophet (peace and blessings be upon him) said: "Make him swear by Allah." He said: "If I make him swear by Allah but he does not desist?" The Prophet (peace and blessings be upon him) said: "Seek help against him from the ruler." He said: "If the ruler is far away (and access to him is not possible)?" The Prophet (peace and blessings be upon him) said: "Seek help against him from other Muslims." He said: "If there are no Muslims there either?" The Prophet (peace and blessings be upon him) said: "Then fight him, until you protect your wealth or become among the martyrs of the Hereafter."

Narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever is killed while protecting his wealth is a martyr.

Narrated by Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Whoever is killed while opposing oppression is a martyr.
