I totally agree; I mentioned that in my post. In a binder, without the Arabic word, Koran on it, and presented by a Christian delegation, it totally makes sense that he did not realize it was a Koran, if indeed it was. Gospel readings, which is what some of those who say it was not a Koran say it was, might very well be put into a binder; I can’t picture a binder of a Koran.
I don't think the picture is clear enough to be able to certainly say that.
