In contrast, the Bible was written long after the times of previous prophets and contains additions and deletions. The chapter argues that it is illogical to believe that Muhammad authored the Quran given its scientific truths and literary excellence. It provides opinions from important non-Muslim scholars who have been impressed by the Quran's style and contents. In the end, the chapter invites open-minded scholars to study the Quran to realize it could not have been written by a human.
