There is a trait in the Qur’an that does not exist in any other book. When the Qur’an mentions certain information it would say to the reader “You knew it not before this”. There is not any manuscript that says “You knew it not, neither you nor your people, before this” (Hud: 49) Amazingly, the polytheists of Makkah who were in a fierce enmity with Islam did not disclaim this information saying that they are not new, or that they know from where Muhammad (Peace Be upon Him) bring or they already know it!! They could never challenge the information because they were really new to them.
