How did the muslim policy of ruling conquered peoples compare with that of the byzantines and the persians

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.
