Therefore, one of the Muslim leaders, namely Mohammed Abid Jābirī who is one of the phenomenal figures of revolutionary Islamic thinkers with his theses on various real advances in human life, both in his studies of: the social environment or the development of sacred texts Muslims, which in this case is specifically in the study of the relationship between Religion and the State, Democracy, Khilafah Theory, and Religious Reform through renewal of knowledge. That is what later became the main and interesting discussion to be examined through the relationship approach between Religion and the State through the framework of a fundamental, secular and substantive school of thought. The analysis of MA Jābirī's views on religious reform and knowledge renewal focused on the relationship between Religion and the State in the Modern Age, which was then analyzed by the author using a combination of Al-Mawardi's views in Al-Ahkam Al-Sulthaniyyah, Agus Maftuh Abegebriel and Ahmad Yani Abeviero through his paper Negara Tuhan; The Thematic Encyclopaedia, and the development of democratic issues in the Islamic and Western world as an inseparable relationship when discussing Religion and the State as substantic.
