Sheikh Bedreddin Simāwī (d. 823/1420), who has an important place in Turkish social and political events, XIV. and XV. He is one of the important fiqh scholars and Sufi who lived in the centuries. Sheikh Bedreddin, who defends the idea of, waḥdat al-wujūd has a rebellious and bureaucratic identity. Although Sheikh Bedreddin was a distinguished scholar in the field of fiqh and Sufism, his scientific personality could not be adequately addressed due to the rebellions in which his name was involved, so his activist personality came to the fore. But, Sheikh Bedreddin attracted attention due to the different interpretations he brought to the Islamic belief. Sheikh Bedreddin has many works in areas such as Tafsir, Fiqh, Nahiv and Sufism. His work named Wāridāt is among the most discussed books in Sufism literature. In this work, Sheikh Bedreddin, who voiced his theological views, was criticized by the Ottoman scholars on the grounds that he broke people's beliefs, especially denied doomsday and resentment, and was accused of being atrocious. The purpose of this study is to determine the theological views of Sheikh Bedreddin in the context of his work named Wāridāt. In this study, Sheikh Bedreddin wrote his Wāridāt with the understanding of waḥdat al-wujūd, such as absolute existence, hereafter, angel, jinn, devil, heaven, hell, etc. It was determined that he interpreted theological issues in the context of verses and hadiths with a different perspective and displayed a stance with innate ideas that went beyond the belief of Islam over time.
