On lack of separation church/state
Separation between church and state- not an option for Muslims since it requires to replace God-given beliefs with man-made beliefs.
Dr. Jaafar Sheikh Idris, in “Separation Of Church And State” said: “So how are Muslims to approach the modern trend of separation of religion and state in their countries? The basic belief in Islam is that the Qur’an is one hundred percent the word of God, and the Sunna was also as a result of the guidance of God to the Prophet peace be upon him. Islam cannot be separated from the state because it guides Muslims through every detail of running the state and their lives. Muslims have no choice but to reject secularism for it excludes the laws of God.
Supporters of the secular state argue that the values of one religion cannot be imposed on members of different religions that are present in our countries. However, whether the non-Muslims in a state are few or many, secularism is not the answer. The non-Muslims in Muslim states will either be secularists themselves, in favor of abandoning the laws of Islam in the state, or will be devoted followers of their own religion, who wish that the state follow the rules of that religion. So in either case, a compromise cannot be made in accordance with the Islamic point of view. What needs to be pointed out is that under the law of Islam, other religions are not prohibited. At the same time, people are provided with doctrines for legislation and running of state that will protect people of all faiths living in the state.
Secularists in the West will agree with this, then they will point out that under Islamic law, people are not all equal. No non-Muslim, for example, could become the president. Well, in response to that fact, in turn, secularism is no different. No Muslim could become president in a secular regime, for in order to pledge loyalty to the constitution, a Muslim would have to abandon part of his belief and embrace the belief of secularism — which is practically another religion. For Muslims, the word ‘religion’ does not only refer to a collection of beliefs and rituals, it refers to a way of life which includes all values, behaviors, and details of living.
Secularism cannot be a solution for countries with a Muslim majority, for it requires people to replace their God-given beliefs with an entirely different set of man-made beliefs. Separation of religion and state is not an option for Muslims because is requires us to abandon God’s decree for that of a man.”
