Concepts and Ideas at the Dawn of Islam [PDF ebook] 

This book deals with the history of pre-Islamic Arab society and the emergence of Islam, as reflected in hadith, adab, historical, genealogical and exegetical literature. Among the themes discussed are the ethnic composition of the population of Mecca, the evolving relationship between the nascent state in Medina and Muslim religious ideas, as well as some aspects of early Muslim expansion. Other articles deal with Jahili tribal groups and their contribution to emerging Islam. An extensive article is devoted to Adam as a great herald and predecessor of Muhammad.
