It is narrated from Sayyiduna Abdullah bin al-Zubayr and Sayyiduna Abdullah bin Amir bin Kurayz (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is killed protecting his wealth" or he said: "Whoever loses his life defending his wealth, he is a martyr."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abdullah bin Amir (may Allah be pleased with him) only with this chain, and Abdullah bin Mus'ab bin Thabit is alone in narrating it."
