Indonesia has a diversity of local religions that have lived hundreds of years before independence. Currently, local religions are known as adherents of belief. In its history, adherents of this belief have experienced ups and downs to gain recognition from the State. For this reason, legal protection for adherents of belief is needed, which is then linked to Siyasah fiqh to understand the relation to Islamic law regarding adherents of belief. The purpose of this study is to determine the protection of the rights of adherents of beliefs in Indonesia, and to protect the rights of adherents of beliefs in Indonesia from an Islamic perspective. This research is a type of library research, data sources were obtained from literature searches such as journal articles, internet sites, books, legal materials (laws), as well as other research results relevant to this research topic. The results of this study are that the protection of the rights of adherents of faith in Indonesia has previously experienced discrimination and recognition that has ebbed and flowed from period to period. The graph gradually increased after the reformation, decreased slightly after the promulgation of the Population Administration Law and gradually increased again after a decision was made on an application submitted by adherents. protection of the rights of adherents of belief in Indonesia from an Islamic perspective is that Islam regulates freedom of religion and belief, protects the rights of citizens even if they are non-Islamic with a foundation of human unity, that Islam has the principles of Al-Adalah (justice), Al-Musawah (equality ), Karomah insaniyah (human honor) and so on, and this is as contained in Islamic teachings, and in accordance with the 1945 Constitution.
