This research aims to understand how the aspects of aqidah (creed), fiqh (jurisprudence), and akhlaq (morality) become fundamental elements in the perspective of Islamic teachings, and how the philosophical, juridical, and sociological aspects in the teachings of Indonesian Positive Law also serve as fundamental foundations for the Indonesian legal system. The study uses a literature or library research method to compare these two distinct concepts, which is typically viewed as a comparative study. The results indicate that the legal knowledge built within Indonesian Positive Law is fundamentally linear with the view built by Islam, particularly concerning the fundamental aspects of Aqidah, Fiqh, and Akhlaq in relation to the philosophical, juridical, and sociological aspects of Indonesian Positive Law. Both systems are closely related. However, the author finds that the Islamic view looks deeper, not just at the group level, but also at the aspect of human development towards individual human beings. The philosophy of Islam, according to the author, looks deeper: the development of the individual human being can give rise to good cultural group development concerning their tawhid (monotheism), fiqh, and their relationship with other human beings.
