Quran and hypotheses of its similarity with human's words

the author pointed out to the fact that it is impossible for human beings to adapt God’s words with his understanding, at the same time that the surface of Quran is understandable for people but its exact concepts need an interpretor and commentator from out side; this does not decline Quran’s reasoning. Quran’s Omnipresence and ever lasting nature necessitates two layers for Quran, an outer and a deeper layer. The interpretor of this deeper layer should be introduced by God. The author endorsed his claim by logical and traditional reasons.
