This is an undergraduate college textbook, and it reads like one. I found it interesting, though the style is rather dry. I appreciated the history of Islam being provided in the context of the religious ferment that was going at the time -- particularly the unorthodox Christian sects that had been driven out of the Byzantine empire into the desert regions. Mohammed apparently had contact with several of these groups during his travels, and his views and perspectives on Christianity were influenced by their theology. It was also interesting to read how in the early years, Muslims and Jews found common cause in their opposition to Christianity. All in all, an excellent overview of the history of Islam, the major (and minor) Islamic sects, Islamic theology, interpretations of Islamic law, etc. If you want an objective, non-polemic introduction to this important religion, this is a good one.
