Understanding the Koran

Best insight was learning about the Islam misunderstanding of the Old Testament, this is very useful to show that the Quran is not inspired as claimed.

The author in my opinion is actually too kind to Islam, stating that Islam is akin to

John 4:22 - You worship what you do not know; we worship what we know, for salvation is from the Jews.

However I think it is much clearer upon studying Muhammad that he was in fact visited and influenced by satan.
