I say we go back to the Islamasperging
It's not all that impressive that Muhammad, though illiterate, could mentally compose and recite the Quran. If he's illiterate then of course he'd have to dictate it. That he could remember it is also no grand feat as the Greeks orally transmitted the Iliad and Odyssey (much more impressive works) over a thousand years earlier. If anything, composing in verse makes it easier to remember. Also, keep in mind he composed over decades. He didn't think up the Quran in a week, he had years upon years to compose verses, memorize them, and after reciting them thousands upon thousands of times, add a couple new verses every other year. Besides, Hadith like the Satanic Verses incident show that he didn't always recite perfectly, and if the mistake wasn't blaringly obvious like in that case, who's gonna call him on it? The Quran isn't in writing yet so who could double check him? The few he tasked with memorizing the Quran? If he recites and fucks up a few words here or there, they'll just assume they remembered wrong and commit to memory the version the prophet just said.
And that's assuming Muhammad's oral tradition had anything to do with what was written down decades after his death.
