: This article analyzes the life and scholarly heritage of Burhanuddin al-Nasafi (approx. 600/1203–687/1288), an outstanding representative and encyclopedic scholar of the Mawarannahr school of Kalam in the 13th century. The research examines the historical paradox related to the scholar's personality – the discrepancy between the extreme scarcity of biographical information about him (particularly regarding his teachers) and, at the same time, his high recognition as the “Sheikh of Baghdad's philosophy”. The article analyzes al-Nasafi's international activities (Nasaf, Delhi, Damascus, Baghdad), his belonging to the Maturidi school through the prism of his views on the issue of “the faith of the muqallid” (iman al-muqallid), as well as the circle of his outstanding students, such as Ibn al-Fuwati, Shamsuddin al-Samarqandi, and A'lamuddin al-Barzali. It also reveals the centuries-old bibliographical confusion surrounding the scholar's major works, such as “Kashf al-Haqa'iq” (tafsir) and “al-Fusul al-Burhaniya” (jadal) (including their erroneous attribution to Fakhruddin al-Razi and Muwaffaquddin al-Kawashi), and provides methodological evidence of their true authorship.
