"Al-Ghazali: A Study in Islamic Epistemology" is a book written by Mustafa Abu Sway that explores the development of Al-Ghazali's epistemology. The book questions the claim that Al-Ghazaliy abandoned Sufism for the method of the traditionalists. It analyzes Al-Ghazali's approach to acquiring certainty, methodological scepticism, foundationalism, attitude to authoritative instruction (taʿlim), and philosophical demonstration and Sufism in his epistemology. The book is a valuable resource for scholars of Islamic philosophy and Sufism.
