There is no any religious scripture that many people have memorized from beginning to the end except the Qur'an. This is a well-known fact even among the non Muslims living in Islamic countries . In fact, if all the books and all the electronic computers in the universe were to be destroyed completely, it is only the Qur'an that can be recovered word for word. This miracle of memorizing the Qur'an is foretold in the Qur'an many times in a repeated manner where God Almighty declare as follows: INDEED, WE HAVE MADE QUR'AN EASY TO REMEMBER; IS THERE ANYONE WHO WILL TAKE IT TO HEART ? (Qur'an 54:17, 22, 32, 40). Of course, this prophecy and assurance is beyond the imagination and capability of any human being. The fulfilment of this prophecy is even enough to prove that the Qur'an is a divine word of God. Again, see how the word "Qur'an" is mentioned in the Qur'an. This is not true with any other religious scripture. For example, the word "Bible" cannot be found inside the Bible. This simply implies that the selection and collation of all the books in the Bible is not something commissioned by God Almighty. You cannot find a single verse in the Bible that unite all the books in the Bible together as Bible talk less of a verse coming directly from God's mouth that would declare the WHOLE of the Bible as divine word of God. Yet the presence of such a verse in the Bible is important and necessary because Bible is not a single book like Qur'an. It is a collection of books written by different author at different time. Therefore, it is either each book in the Bible contains its own evidence of its divine origin or there is a VERSE uniting all the books together as Bible and then declaring such entire Bible as the word of God. In other word, the word "Bible" should be present in the Bible. Not only that; there should be another VERSE that would then declare such ENTIRE BIBLE as something commissioned by God. But this is not so. In Qur'an 20:2-3, God says: WE HAVE NOT SENT DOWN QUR'AN TO YOU( O MUHAMMAD-PBUH) TO CAUSE YOU DISTRESS .BUT ONLY AS A REMINDER TO THOSE WHO FEAR GOD. A REVELATION FROM HIM WHO CREATED THE EARTH AND THE HIGH HEAVEN
