Besides commentary, a translated Koran is not an actual Koran. The only official versions must be in the original Arabic.
And IIRC, swearing by the Koran in any case is itself a blasphemous act.
I believe that it is not written in Arabic but in Old Salic which looks like Arabic and has many similarities but many differences - for instance everyone knows about the supposed 72 virgins martyrs receive on reaching paradise, but the Old Salic says 72 white raisins ... a rare and very valuable commodity in 620 AD in the ME.
BTW Mohammad when asked how big Paradise was, he replied - there is room for 72,000 faithful, no more. There must be a very long waiting list ...
