Fight back against those people of the Book who do not believe in God and the Last Day, nor do they avoid what God and His prophet have declared as unlawful, nor do they adopt the Right way (as prescribed by Islam.) If they want to live in Islamic state, they should give up their hostile attitude and pay a special tax (know as Jizyah in Arabic) in return for protection and other privileges that they get (such as not being obliged to join the “national Islamic army.”)
