The article studies the phenomenon of Ibadism as an Islamic movement and state ideology in the Sultanate of Oman. As a theological branch, Ibadism has significantly influenced political development and changed the history of this country. It has contributed towards Oman's unique path in the global world. Nowadays, non-interference and mediation make the basis of Omani policy. The author focuses on the theoretical pillars of Ibadism and its political background as well as the intellectual heritage of the country. The author uses the example of the activity and life of Abu Muslim al-Bahlani, the outstanding Omani poet, public figure and educator of the end of the XIX and the beginning of the XX century. Abu Muslim al-Bahlani's legacy and life became a symbol of the implementation of Ibadism. His impact was recognized by UNES CO in 2019. Following interdisciplinary approaches, the author concludes that the principles of Ibadism are reflected in his poetry and have been examined in all spheres of everyday life, including art and culture, a fusion of religion and civil consciousness.
