Hazrat Hasan bin Muhammad (may Allah have mercy on him) narrates that the Messenger of Allah (peace and blessings be upon him) wrote a letter to the Magians of Hajr, inviting them to Islam. So, whoever among them accepted Islam, his Islam was accepted. And whoever refused, jizya was imposed upon him. Except that their slaughtered animals would not be eaten, and their women would not be married.
