Within the Islamic Law, the jizya or captation is a per capita tax that Muslim states imposed on non-Muslims who met certain criteria, which were categorized as dhimmis among which were the consideration for being able to practice their faith, meet certain conditions and enjoy communal autonomy, as well as being protected by Muslims from external aggressions and exempt from military service.
The jizya in the Islamic empire was a per capita tax which was established every year by Islamic states on some non-Muslim subjects.
Explanation:
This kind of tax was established because there were some Muslim lands under the control of Islamic laws as a way to remember that Muslims were in a lower status.
The Muslim citizens consider that the jizya was a way to defend their country. That's the reason why non-muslims who live in a Muslim state and at the same time are protected by the state, must pay this tax as they are not required for defending the country.
Nowadays, this tax is not applicable anymore but it is a way to keep the traditions.
