This research is a kind of non-doctrinal qualitative legal research. Data was obtained from the books or literature and it is analyzed to see the correlation between legal substance, legal structure and legal culture. This study concluded that without being Islamic state, there many models that can be used by Indonesian Muslims in transforming or practicing sharia.
