Answer: The Muslims let people keep their religions, while Persians and Byzantines persecuted those who did not follow their religion.
Explanation:
Unlike Persians and Byzantines, who persecuted those who did not obey their faith, the Muslims conceded religious tolerance because the understood that non-Muslims would be less likely to resist them as long as their religions were tolerated, even if they were not actually treated equally.
Jews and Christians did have to pay a poll tax and were ban from converting others. The promised equality and freedom, and then removal of taxes, were an incentive for non-Muslims to convert.
