Al-Ghazālī's Spiritual Crisis and Decade as a Wandering Sufi

In 1095, the renowned Islamic scholar and philosopher Al-Ghazālī (1058–1111 CE) abandoned his prestigious position as head of the Niẓāmiyya Madrasa in Baghdad, a leading academic institution of the medieval Middle East. Despite his intellectual fame, wealth, and the favor of Seljuk authorities and the Abbasid Caliphate, he experienced a profound spiritual crisis. He realized his pursuits were driven by a desire for reputation rather than salvation. After six months of inner conflict, he lost his ability to speak and became physically ill. In late 1095, he devised a ruse to leave Baghdad, pretending to go on pilgrimage to Mecca while secretly heading to Syria. He spent two years in Damascus in solitary prayer and Sufi devotions, then moved to Jerusalem, where he retreated daily in the Dome of the Rock. He performed the Hajj, visiting Mecca, Medina, and the Shrine of Hebron. For a decade, he lived as a wandering ascetic, reportedly sweeping the floors of the Umayyad Mosque under an assumed identity to crush his ego. This transformative period led him from philosophy to experiential Sufism, culminating in his magnum opus, Ihya’ ‘Ulum al-Din (“The Revival of the Religious Sciences”), which harmonized Islamic doctrine with Sufism. He returned to teaching in Nishapur in 1106. His decision to renounce fame and power altered Islamic thought and anticipated later Western skepticism.
