I don't own an actual Koran - but I have several books about it - that break down certain sections of its text - so that when I teach in adult Sunday school, I can better know the subject matter as I contrast/juxtapose Worldviews & help others to make better informed decisions when they're battered by bullsh*t via the media.
Owning such texts obviously doesn't mean I "endorse" Islam, the Koran or their worldview. I does mean I want to make accurate statements about same, so that any opposed to what i do, do not attempt to undermine my statements on the basis that they're false or misleading (which they'll do anyway - but at least I can cite my sources rather than simply say "it's my opinion.:")
I'd also like to know exactly how many missionaries the Mufti of Constantinople sent during that time period & how many "flocked" to hear them utter their brand of worldview.
