The paper analyzes the political and religious activities of Ali Akbar Hashemi Rafsanjani, one of the most famous politicians of modern Iran. His political and religious activities from youth to the end of his life are subject of the study. In particular, three periods of his life are of interest here: his acquaintance with Ayatollah Khomeini and studying, religious activity before the Islamic revolution, and religious activity after the Islamic revolution. It is clear that Rafsanjani paid much attention to the study of the Quran and Islamic law, and after the Islamic revolution, he sought to promote religious ideas and Islamic legal regulations among Iranians. At the same time, after the revolution, Raf-sanjani became very actively involved in the political life of Iran, occupying key positions in the main government bodies, including the presidency, as a result of what his own religious activity decreased significantly, although he nonetheless sought to combine politics and religion. The paper states that Rafsanjani took a moderate and pragmatic political position and changed his views depending on the circumstances in which the country found itself.
