The Mysteries of the Human Soul is a careful English translation of al-Im¿m Ab¿ ¿¿mid al-Ghaz¿l¿'s profound treatise al-Madn¿n bihi ¿al¿ Ghayri Ahlihi, a work devoted to the deepest questions of human existence: the origin of the soul, its relationship to the body, its immortality, and its ultimate return to God. Grounded firmly in the Qur'¿n and the teachings of the Prophet ¿, the work explores themes such as taswiyah (fashioning), nafkh al-r¿¿ (the breathing of the spirit), the indivisibility of the soul, and the metaphysical distinction between the world of matter and the world of divine command (¿¿lam al-amr). Al-Ghaz¿l¿ engages theological reasoning, philosophical critique, and disciplined mystical reflection while maintaining strict doctrinal boundaries and ethical restraint. The book also addresses eschatological doctrines including resurrection, the balance of deeds, intercession, the Bridge over Hell, the punishment of the grave, and spiritual versus physical reward-always framed as matters of belief grounded in revelation rather than speculative metaphysics. Translated with clarity and fidelity, this volume is neither devotional poetry nor abstract philosophy, but a rigorous Islamic inquiry into the soul (nafs and r¿¿) as understood within Sunni theology and classical Sufism.
