How many times do I have to repeat myself?
I'M NOT TRYING TO PROVE THE QUR'AN ISN'T FROM GOD!!!!
I'M NOT TRYING TO PROVE THE QUR'AN ISN'T FROM GOD!!!!

That enough for you?
Now that we've hopefully gotten that out of the way, I'm debating the validity of your condition for the challenge, not the challenge itself. If the condition you've provided, is, in fact, true, than whatever it is that gave the Qur'an to Mohammad would be using fear and bullying tactics to make people convert. That is the domain of the demonic. Therefore, if the Qur'an is from God, your condition cannot be true.
