If you accept Islam, you will receive everything that is for the people of Islam, and upon you will be everything that is obligatory upon Muslims. If you refuse to accept Islam, then I invite you to pay Jizya; if you begin to pay Jizya, you will receive everything that is given to those who pay Jizya, and upon you will be everything that is obligatory upon those who pay Jizya. And if you refuse, then I have with me such men who love fighting as much as the people of Persia love wine.
