 Among the great masters of philosophical mysticism hailing from Spain, Ibn Masarrah (883–931 CE) stands out. He was an ascetic whose views on the mystic quest for unity of the soul with God comprised a major theme in his philosophical mysticism. Others include Ibn Ḥazm (994–1064), who emphasized mystical love, Ibn-Bājjah (1095–1138 CE) who treated the concept of intellectual and mystical intuition as the faculty that experiences Divine realities, Ibn Al-Sid of Badajoz (1052–1127 CE) who developed what some have called mathematical mysticism, and Ibn-Ṭufayl (c. 1105–1185 CE), whose mystical allegory Son of the Living Awake (Ḥayy ibn Yaqẓān) and his concept of Active Intellect, made him a major exponent of mysticism in the Islamic philosophical tradition. Finally there is the Sufi philosopher, Ibn Sab‘īn (1217–1268 CE) who made an effort to bring about a rapprochement between philosophy and Sufism in a systematic treatment of mystical themes.
