Sus (Susa)

Sus (medieval al-Sus, ancient Susa/Shush), in the Khuzestan region of southwestern Iran, was an old city of the lowlands near the Karun plain. The mystic al-Hallaj (executed in Baghdad 922) spent part of his early life in the Sus/Tustar region of Khuzestan, where he was associated with the circle of Sahl al-Tustari.
