Muhammad ibn Abd al-Jabbar al-Niffari's 'Kitab al-Mawaqif' (The Book of Stations) and 'Kitab al-Mukhatabat' (The Book of Discourses) are seminal works in Islamic mysticism. Al-Niffari, a solitary tenth-century Sufi, presents his profound spiritual experiences and divine communications in a distinctive, aphoristic, and often paradoxical style. These texts offer unparalleled insights into the nature of divine knowledge, the seeker's journey, and the challenges of ultimate spiritual realization. This edition, meticulously prepared and translated by the renowned orientalist Arthur John Arberry, makes these challenging yet deeply rewarding Sufi masterpieces accessible to a wider audience, providing a critical study of Al-Niffari's unique contribution to Sufi thought.
