It should be pointed out here that while Jizya tax was collected from able-bodied non-Muslim adult males who did not volunteer to join war efforts in a Muslim-administered country, a similar form of war tax was also collected from able-bodied Muslim adult males who refused to join war efforts to defend the country. There was, therefore, no discrimination between able-bodied Muslim males and able-bodied non-Muslim males when it came to the payment of war-tax, as long as the person in question would not volunteer in war-efforts for defense of the Muslim-administered state. Zakat (2.5% of savings) and %u2018Ushr (10% of agricultural products) were collected from all Muslims, who owned some wealth (beyond a certain minimum, called Nisab). They also had to pay sadaqah, fitrah and Khums. None of these taxes were collected from any non-Muslim. As a matter of fact, the per capita tax collection from Muslims was several fold that of non-Muslims. I would also like to state here that before the advent of Islam in India, Rajputs living in western India used to collect a similar form of Jizya or war tax which they called "Fix" tax. (Ref: Early History of India by Vincent Smith) War tax was not a sole monopoly among the Indian or Muslim rulers. Historian Dr. Tripathy mentions a number of countries in Europe where war-tax was practiced. (Ref: Some Aspects of Muslim Administration by Sri Tripathy)
