if a book contains an error i can't trust it's credibility, let me give you an example, let's say that the quran contains error which is really too clear like for example to mention that Moses was after the jesus peace to be upon both, this is a fatal mistake, so how i could trust the quran when it said to me that Jesus wasn't god, or to worship Allah only, i can claim and said maybe it's wrong too, a book from the god is revealed in order to follow it, so it should be totally correct in order not to leave a Justification for non-believers to use, errors or contradictions in a holy book make it un holy, and so no body will accept it except who just follow their desires
i'd like to know what's errors are you talking about??, errors in our actions or errors in our creation or it's another?
