This is the first major study in a Western language of Rashid al-Din Maybudi's Persian commentary on the Qur'an Kashf al-asrar wa 'uddat al-abrar (Unveiling of Mysteries and Provision of the Righteous).Annabel Keeler explores the interplay between scriptural exegesis and mystical doctrine in a twelfth-century Sufi commentary on the Qur'an.Previously little-known outside the Persian-speaking world, it is increasingly recognized as a key work in the development of Sufi Qur'anic interpretation.This volume provides invaluable background for anyone wanting to gain a deeper understanding of Persian mystical poetry and prose, and other major works of Sufi literature.
