The Qur'an/YMMV


 * Broken Base: Easily the second most controversial work in the history of the literature, through most of it involves internal debates between muslims, that amount to billions of people anyway, since non-believers are nowhere near interested on it. There is a pretty obvious reason for it: the most controversial parts of the book are taken from The Bible, so it feels redundant.
 * Fair for Its Day: Most Double Standards, e.g about women and men, were rather progressive in their time.
 * Overshadowed by Controversy: The book is heavily associated with imperialistic attempts at conversion, first by Arabs and then by ottomans. Not much different from the Bible, sure, but most people know through pop-culture the content of that book, so much it names multiple tropes on this very site. The Qur'an is nowhere as nearly as quoted.
