Fortunately(yes, fortunately), such a book will probably never be published in our country since it hardly holds any commercial value... so I've never read that book.
If I may judge by the total waste of crap the website spews, I seriously advise other people to take up a well translated version of the Kur-an before reading that book.
Arabic is very 'poetic' language in nature, and nuances and meanings vary carefully upon each text. Unfortunately, that point has been brutally exploited by Christian radicals to portray it as a demon's religion.
How could they not do so?
The Islam faith conquered almost all of the southern/eastern half what used to be the old Roman empire in about three centuries. The Christians of the 'Old faith' were actually welcoming Arabic conquerors - only taxes were issued to the conquered territories which were at a much lower rate than the Byzantine Empire collected. They were free to keep their religion.
If any Christian should turn Muslim, he was rid of his tax duties forever - which caused mass conversions of Christians to Muslims. Later on, the Islam officials actually had to try and convince their new subjects to STOP converting to Islam... and then finally, got rid of the policy of non-taxes to the first and second generation of newly converted Muslims.
I'm sorry to say that the spitting image of terror and doom, was what the Christian world was like in the old days, rather than what Islam was like. Basically what it says on the website is a 'wishful thinking' of a fanatic.
I've studied a bit in Islam and the Kur-an, not deeply though, but if I'm correct, the first shown verse of Ishaq:471 on the website, is a typical case of deliberate misinterpretation - it goes more like this;
"We are given a prophet who shall unite all the men, and bind them to our faith"
It may sound simular, but notice that the nuance is totally different. Basically they are praising their prophet whom they believe God has sent, so many people shall benefit from his wisdom and enlightment. The website turns it into a prophecy of the arrival of an Antichrist or something.
