This scholarly study investigates the role of intelligence and information-gathering within Islamic civilization. Muhammad Husayn Araji examines how political authorities, administrative institutions, and intellectual traditions shaped practices of surveillance, communication, and strategic knowledge. Rather than treating intelligence as a modern invention alone, the book situates it within the broader history of Islamic governance and social organization, exploring how rulers and institutions collected, interpreted, and used information. The work connects questions of statecraft, intellectual life, and political authority, showing how concepts of knowledge and practical administration intersected in premodern Islamic contexts. Written for readers interested in Islamic history and political thought, it offers a focused contribution to understanding the historical foundations of intelligence practices.
