It doesn't "have" it, it "Is" it.
No, the book itself from the offset is a transmission, a direct revelation to Muhammad and the rest of humanity. This is what the book says about itself, not Muslims later on.
I think you are uncomfortable with the idea of divine revelation, so be it, your tag says "anti-theist", so it doesn't surprise me that you'd be triggered by such a concept.
In Buddhism we have concepts that have vague connections to such ideas (as revelations) but not on the grandiose universal scale as Islam. We believe there are other realms and intelligences out (or in) there we can connect with within the sphere of reality.
I don't think there's anything even remotely bad about the Qur'an, in my own experience. As I said, it's far better than anything in the Bible, hands down. The Bible is disturbing and offensive.
The only difference is Christians believe such things were "inspired", whereas Muslims have to deal with the intellectual science of Hadith analysis which is not a 'grab all' situation, it scrutinizes heavily. Most Muslims are aware that there are very revolting things in the Hadith, but they're not (except for Salafis) naive enough to accept such things just because it's in a Hadith collection on the basis of that alone.
The Qur'an is an entirely different thing to that again, and the Qur'an itself urges readers/listeners to reflect and meditate on it's verses. I really don't think you Icehorse, with all due respect, have much of a case.
