Abu Hamid al-Ghazali (1058–1111) was one of the most influential thinkers in Islamic history, a theologian, philosopher, jurist, and mystic whose ideas transformed Muslim intellectual and spiritual life. Born in Persia, he rose to prominence as a distinguished scholar and became a leading professor at Baghdad’s prestigious Nizamiyya madrasa. Despite his remarkable academic success and public reputation, Ghazali experienced a profound spiritual crisis that led him to abandon his position and embark on a journey of self-examination, seeking a deeper understanding of faith beyond worldly recognition and intellectual achievement.

This volume explores Ghazali’s remarkable intellectual journey and his efforts to reconcile Islamic theology, philosophy, and spirituality. His celebrated work, The Revival of the Religious Sciences (Ihya’ Ulum al-Din), sought to reconnect religious practice with inner sincerity, moral discipline, and spiritual awareness. In The Incoherence of the Philosophers, he challenged influential philosophical doctrines, raising fundamental questions about reason, revelation, and the limits of human knowledge. Rather than simply rejecting intellectual inquiry, Ghazali examined its possibilities and limitations while emphasizing the importance of spiritual experience in the pursuit of truth.

Part of the Makers of the Muslim World series, this book examines the life and legacy of a thinker who helped reshape Islamic theology and religious practice. Ghazali’s enduring influence lies in his effort to unite outward observance with inward transformation, offering generations of readers a profound vision of faith, knowledge, and the human search for meaning.
