Though Ibn Khaldūn is renowned for the Muqaddima and the ‘Ibar—which are considered milestones in the fields of medieval sociology and the philosophy of history—little is known about his religious and spiritual life. In her introduction to Ibn Khaldun on Sufism, Dr Yumna Ozer seeks to restore Ibn Khaldun and his work to the context from which his theories arose, both in intellectual and religious terms; she also draws a vivid painting of Sufism in the fourteenth century and rethinks Ibn Khaldun’s relationship with Sufism. The translation itself addresses the dichotomies or synergies between religious law and the Sufi path, the roles played by jurists, and that played by Sufis, and the particular position of the Sufi shaykh or spiritual master.
