This implies that the word of God which is in the Holy Quran, has been sent down to us in utmost perfection and in truth and justice, and that, no one can alter it or even change a phrase of the Book, as it was done in the case of the Bible of Moses, and the Gospel of Jesus. This is because Allah has promised that in Quran S15: 8: ``It is Me who have sent down this Quran as a reminder, and We will assuredly protect it.'' Therefore our Holy Book which is named `QURAN' has been sent down perfect and in truth and justice from our Gracious Lord, and men cannot change, alter, or pervert even a word of the Book, as it has already been protected so far, and throughout ages! This is because Allah Himself will look after His Book of Guidance, and will protect it from any destructive hand! VERSE NO. 115
