Why I recommend "The Prophet and the Age of the Caliphates: The Islamic Near East from the 6th to the 11th Century (2nd Edition) (History of the Near East)" — 3 years ago
One of the best serious introductions to early Islamic history. Examines the rise of Islam in the Arabian context, the early Islamic communities, and the Ummayyad, Abbasid and Fatimid caliphates.
