Re: why other Books were not protected??
The torah again was written by humans. It was rewritten a few times by the jews to fit their own mandates.
The Quran was written down on leaves and on skins before it was transcribed on to paper. I was reading somewhere that 69% of the Quran was written down in varous cloths an other items before it actually became a book.
last paragrpah makes quran more adhoc if what u are sayng is right.. just resaon with urself chit cloths skins pieces having info and then someone compiling it.... i don't see why how when this became fool-proof system.. sounds like crude way of doing things
