Sufism: The Spiritual Revolution in Islam – by Abu Alaa Afifi is one of the most important works of Dr. Abu Alaa Afifi, a prominent Arab scholar in Islamic philosophy and Sufism. This book addresses Islamic Sufism as a profound spiritual and intellectual movement that arose from the human soul's need for transcendence and purification from materialism, associated with the quest for divine truth and inner knowledge.

Afifi provides a comprehensive analytical study of the evolution of Sufism from its inception to the completion of its features in the major schools of Sufi masters like Al-Hallaj, Ibn Arabi, and Al-Ghazali. It also covers fundamental concepts such as asceticism, love, annihilation, knowledge, and union.
