AFAIK all major religions have their 'holy' books and all of them consider
those books to be free from error.  Fundamentalists of all stripes consider
*every* single word in their holy books to be absolutely, incontrovertibly
true - in the case of fundamentalist Christians (and presumably others)
despite a considerable body of evidence to the contrary.

I've only scanned parts of the Koran and can't really comment on it.

WRT the Bible at one time or another I've read most of it at least once.
There are *lots* of things mentioned in the Bible that (a) are no longer
relevant, (b) never occurred, (c) are not supported by any other source
and (d) are flat-out wrong.  Some things described in the Bible have
archaelogical evidence of that occurrence - Noah's flood is one such - or
existence - the Walls of Jericho being one example.  The bottom line is
that AFAIC, *some* Biblical events are true but the Bible itself is not
inerrant because some other things in the Bible are not true.

Note that there is also archaeological evidence of occurrences mentioned in
ancient writings other than the Bible - the city of Troy, from Homer's Iliad,
comes to mind.  But then AFAIK neither the Iliad nor the Odyssey are considered
'holy' books.
