Fate: Fazlallah Astarabadi (~1340–1394 AD) was executed on the orders of Timur’s son Miran Shah. His followers were persecuted across Persia, Anatolia, and Azerbaijan. The movement survived underground, influencing the Bektashi Sufi order and leaving traces in Alevi and other heterodox traditions. Their texts were banned and burned.

Fazlallah Astarabadi developed a system of letter mysticism: the 32 letters of the Persian-Arabic alphabet contain the secrets of creation and divine reality. The human face is a microcosm of these letters — the divine word made flesh. At the extreme: Fazlallah implied he himself was the manifestation of the divine word, a messianic figure. The Hurufiyya combined Sufi mysticism, Shia esotericism, and numerological speculation into a syncretic system that orthodox Sunni scholars viewed as straightforward shirk (associating partners with God) and the civil authorities viewed as politically dangerous messianism. The movement illustrates a recurring pattern in Islamic history: Sufi mystical experience pushes toward union with God, orthodox theology insists on the absolute distinction between Creator and creature, and the result is periodic execution of mystics who express the union too literally.
