This comprehensive four-volume work by Maytham Janabi explores the life, theology, philosophy, and Sufi thought of the influential Islamic scholar al-Ghazzali. Published in Arabic by al-Mada in Damascus in 1998, the study delves into al-Ghazzali's intellectual synthesis across multiple disciplines, examining his contributions to Islamic theology (al-lāhūtī), philosophy (al-falsafī), and mysticism (al-ṣūfī). The volumes provide a detailed analysis of al-Ghazzali's doctrinal positions and his enduring impact on Islamic intellectual history, making it a significant resource for scholars of Islamic studies, philosophy, and Sufism.
