Jizya is the tax the Qur’an and Islamic law levy on “the People of the Book” as the hallmark of their submission to and subjugation by the Muslims.
“Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued.” (Qur’an 9:29)
A hadith depicts Muhammad saying: “Fight against those who disbelieve in Allah. Make a holy war…When you meet your enemies who are polytheists, invite them to three courses of action. If they respond to any one of these you also accept it and withhold yourself from doing them any harm. Invite them to (accept) Islam; if they respond to you, accept it from them and desist from fighting against them…. If they refuse to accept Islam, demand from them the Jizya. If they agree to pay, accept it from them and hold off your hands. If they refuse to pay the tax, seek Allah’s help and fight them.” (Sahih Muslim 4294)
