: Formalization of an Islamic Law Paradigm in Indonesia. Formalization of Islamic law in Indonesia in principle is an effort of transformation of substantive values of Islamic Law within the system of National law. Indonesia is a constitutional state, so the formalization of Islamic law must refer to the constitution of the state. Therefore, the transformative paradigm of the means of formalization of Islamic law within the constitutional system is an appropriate choice and provides for broader prospects. Thus, the formalization of Islamic law in formal symbolic manner, especially in an effort to establish an Indonesian Islamic State, will only undergo distortions and will not provide benefits for the Islamic community in Indonesia.
