In the early seventeenth century, leaders of Christian countries, Protestant and Catholic, thought that their opposite numbers were turning people into candidates for hell. As a result, they slaughtered one third of the population of Europe. As a result, these European countries, still predominantly Christian, accepted the separation of church and state, in other words, they put the coercive power of government on the one hand, and religious fervor on the other, in different hands.
Whether Muslims can do this or not remains to be seen. The Bible doesn't tell you how to govern, and it was written for people with zero political power. The Qur'an, on the other hand, was written with governance in mind, and it was applied in the first instance by people who ran a state. Whether Islam can exist with a separation of religion and government is the question.
