The Indonesianization of Islamic law, namely by legislating or codifying Islamic law through the state system so that it is enforceable in Indonesia. This study is conceptual research using a legal philosophy approach to comprehend an Islamic legal thought from a sharia scholar using the content analysis method. The results of this study show that the concept of Indonesianisation of Islamic Law uses a modern knowledge system as the paradigm.
