 Suhrawardī’s illuminationist philosophy has influenced many philosophers who wrote major commentaries on gnostic and Sufi texts, among whom are Qutb al-Dīn Shirāzī (1236–1311 CE), Muḥammad Shahrazurī (d. 1153 CE), and Ibn Turkah Iṣfahānī (c. 1362–1433 CE) Following Suhrawardī there is an even closer nexus between philosophy and mysticism. A number of rationalistic philosophers who adhered to Sufi ideas and often practiced Sufism, became exponents of philosophical mysticism. The post Suhrawardīan philosopher-mystics, who continued to refine the rapprochement between philosophy and mysticism, have come to be known as the “School of Shirāz.”
