PLEASE if your interested in learning about ISLAM the religion then looking it up on the web is much more usefull and truthfull than this garbage. you will not be introduced to anything in this short introduction, except the same ani-islamic propaganda that is abundant every were around you.
The author begins by complaining that such a short introduction can't adequately present Islam. Fair enough, but Ruthven then proceeds to waste much time critiquing certain points of view rather than just giving an exposition. Even worse, he often makes offhand allusions to people and historical events and takes an abstract, high-handed tone, so that I feel I would have to already be acquainted with Islam and the history of the Arab world in order to understand what he's talking about. Jeez, this was supposed to be an intro, not a refresher!
