This article examines the concept of Sufism and spiritual ethics in the works of the renowned Islamic scholar and mystic Hakim al-Tirmidhi (c. 820–932 CE), one of the most influential representatives of early Islamic spirituality in Central Asia. The study analyzes his major works, including Khatm al-Awliya, Bayan al-Farq bayn al-Sadr wa al-Qalb wa al-Fu'ad wa al-Lubb, and other treatises devoted to spiritual purification, sainthood, moral perfection, and the inner dimensions of faith.
