Nice appeal to authority, Keyplus!
And who is this world wide expert Dr Campbell of which you speak? The only Dr William Campbell of whom I can find a trace at Case Western Reserve University (or indeed anywhere on the www) appears to be a medical doctor, which doesn't seem to be a tremendously good qualification for talking on subjects like cosmology. He's also a Christian, and may even have highly suspect views on science himself, especially if he's a young earther or IDer.
That aside, it seems to me that to declare Dr Naik the winner of the debate is to ignore Dr Campbell's demolition of Dr Naik's views, and the numerous omissions in Dr Naik's defence of the Koran, such as when he ridicules the Bible for its claim that the moon has its own light, but omits to mention that the Koran makes precisely the same claim.

has quite a demolition of Dr Naik's position. Not nearly so clear as you would have us believe.
(It's always entertaining to watch one lot of religionistas get on their high horse about the obvious errors in another bunch's book without being able to apply the same logic to their own text)
As for your claim that the Koran is not copied from the OT, it's rather laughable considering it dates from many hundreds of years afterwards. Given that many of the stories do not have suffiencient detail provided to make sense unless the authors expected their readers to have a familiarity with the OT stories, it seems a little pointless trying to argue that black is white.
Not that that generally stops those of a religious bent when it comes to defending ttheir books.
