You talking about 1 book out of the 3 that are considerd holy books in islam. I don't know if what you are stating is factual correct as this is the first time i heard about it. But i wil do my research. On the other hand the Hadith and the Sunah are made by seeing how the profet lived and is a account of the witnesses of the profet.

Those books are around for nearly as long as the religion is present. And the oldest books found state exactly the same as those distributed now. So how do you explain that?
