In Sunni Islam tradition, the scope of "khums" tax has been "ghanim", which is defined as the spoils of war. In Shia Islam tradition, states Abdulaziz Sachedina, the scope of "khums" tax has included, (1) booty ("al-ghanima"), (2) objects obtained from the sea ("al-ghaws"), (3) treasure ("al-kanz"), (4) mineral resources ("al-ma'adin"), (5) gainful earnings ("arbaah al-makaasib", business profits), (6) the lawful ("al-halaal") which has become mixed up with the unlawful ("al-haraam"), and (7) land which is transferred from a Muslim to a dhimmi (a free non-Muslim who is adheres to the law and is protected by the fact he resides in that Islamic State) by the latter's purchase of it. The recipients of the collected "khums" have been the descendants of Muhammad and the Islamic clergy.
