forms of this view. The liberal Islamic view is influenced by Muhammad Abduh's emphasis on the role of reason in understanding religion. It stresses democratic principles based on pluralism and freedom of thought. Authors like Fahmi Huwaidi and Tariq al-Bishri have constructed Islamic justifications for full citizenship of non-Muslims in an Islamic state by drawing on early Islamic texts. Others, like Mohammed Arkoun and Nasr Hamid Abu Zayd, have justified pluralism and freedom through non-literalist approaches to textual interpretation. Abdolkarim Soroush has argued for a "religious democracy" based on religious thought that is democratic, tolerant, and just.

Proponents of Islamism (political Islam) reject secularist views that would limit Islam to a matter of personal belief and insist on implementation of Islamic principles in the legal and political spheres. Moreover, the concept of 'Separation of Powers' was propounded by Ruhollah Khomeini. Muhammad Iqbal The modern Islamic philosopher, Muhammad Iqbal, viewed the early Islamic Caliphate as being compatible with democracy. He "welcomed the formation of popularly elected legislative assemblies" in the Muslim world as a "return to the original purity of Islam." He argued that Islam had the "gems of an economic and democratic organization of society", but that this growth was stunted by the monarchist rule of Umayyad Caliphate, which established the Caliphate as a great Islamic empire but led to political Islamic ideals being "repaganized" and the
