The Preaching of Islam: A History of the Propagation of the Muslim Faith

A historical account traces the spread of Islam after Muhammad's death, weighing the effects of early Arab military conquests against other causes of religious expansion. It argues that migration, theocratic state structures, and local social and economic conditions shaped conversions as much as force. The narrative examines missionary activity, the roles of Arab tribes and local communities, and administrative and religious institutions that sustained the faith. Emphasis falls on primary sources and careful citation to support interpretations, and the work combines chronological narrative with thematic analysis.
