The article explores the reflection of the scholarly heritage of Tirmidh scientists in the famous work "Fasl ul-Khitab bi-Wusuli-l-Ahbab" by Khoja Muhammad Porso (1349–1420), a prominent theorist and leading figure of the Naqshbandiyya Sufi order. From a source-critical perspective, the study analyzes how the author utilized the works and Hadiths of the great scholars of Tirmidh – Imam al-Tirmidhi, Hakim al-Tirmidhi, and Muhammad ibn Hamid al-Tirmidhi – to resolve complex theological (aqidah) and Sufi issues. Specifically, the paper examines the high esteem given to the personalities of Hakim al-Tirmidhi and Muhammad ibn Hamid al-Tirmidhi in "Fasl ul-Khitab", clarifying the substance of the narrated Hadiths, spiritual insights, and aphorisms attributed to them. The article is of significant academic value for understanding the profound interconnectedness among the scholarly schools of Mawarannahr and the monumental contribution of Central Asian sages to the evolution of Islamic thought.
