Books You're Not Supposed to Read

From the Politically Incorrect Guide to Islam and the Crusades: The Life of Muhammad: A Translation of Ibn Ishaq's Sirat Rasul Allah, Oxford University Press, 1955. This is an English translation of the earliest biography of Muhammad. It was "written by a pious Muslim" and "virtually every page presents a devastating refutation of the whitewashed, peaceful Muhammad of PC myth".

Here's an idea: If you don't believe it when people tell you how violent the Qur'an is then read it yourself. According to this PIG, the "clearest and most accurate English translation" is The Koran by N.J. Dawood. Muslims tend to dislike this translation because Dawood wasn't a Muslim. The two most accure English translations by Muslims are those by Abdullah Yusuf Ali and Mohammed Marmaduke Pickthall. Both of these are available in multiple editions under various titles however both are "marred by a pseudo-King James Bible English which makes them irritating to read".
Personally, when I have needed to reference the Koran I've relied on the good old internet and gone to http://quod.lib.umich.edu/k/koran/

And a third book that the Politically Correct "Thought Police" don't want you to read is An Introduction to Islamic Law by Joseph Schacht; Oxford; Clarendon Press, 1982. They say that this is "a weighty book, as eye-opening as it is scholarly and that the author "is refreshingly free of the bias that dominates studies of Islam in universities today". A sample from the Mr Schacht's book reads: "The basis of the Islamic attitude towards unbelievers is the law of war; they must be either converted or subjugated or killed."
Definitely NOT Politically Correct :-)
