Quran-The Protected Tablet

Allah Almighty had been witnessing over the Quran.

[10:61] And you are not (engaged) in any affair, nor do you recite concerning it any portion of the Quran, nor do you do any work but We are witnesses over you when you enter into it, and there does not lie concealed from your Lord the weight of an atom in the earth or in the heaven, nor any thing less than that nor greater, but it is in a clear book.

Allah Almighty has been protecting the Quran

إِنَّا نَحۡنُ نَزَّلۡنَا ٱلذِّكۡرَ وَإِنَّا لَهُ ۥ لَحَـٰفِظُونَ )

Lo! We, even We, reveal the Reminder, and lo! We verily are its Guardian. (15:9)

The Quran is called the "Guarded /Protected Tablet" 85:23    لَوۡحٍ۬ مَّحۡفُوظِۭ

لَّا يَأۡتِيهِ ٱلۡبَـٰطِلُ مِنۢ بَيۡنِ يَدَيۡهِ وَلَا مِنۡ خَلۡفِهِۦ‌ۖ تَنزِيلٌ۬ مِّنۡ حَكِيمٍ حَمِيدٍ۬ 41:42  Falsehood cannot come at it from before it or behind it. (It is) a revelation from the Wise, the Owner of Praise. 

For centuries Muslim Ha'afizeen   ( Hafiz?) have guarded the Message of Quran by memorization so, that it's text and prononciation had been correctly , preserved. This is the Miracle of Allah's True Book that it can be memorized by human brain, this way!
