This book examines the theological, philosophical and Islamic mystical dimensions of the Suhrawardî sufi order from the 13th to 15th centuries. The Suhrawardîs were a legally grounded and intellectually vibrant sufi order whose mystical path was based on exchanges and debates on the Qur'an and on the Prophet's customs. The book analyses their interpretation of sacred texts: the Qur'an, hadiths, sunna, and malfuzat. This created a unique self-understanding, which developed specific sufi spiritual exercises. The book discusses new important ways of thinking about the sufi hermeneutics of the Qur'an and its contribution to Islamic intellectual and spiritual life.
