Yes, Al-Ghazali made that point. I don't remember the specific passage but he made the comment that if he left a book in his library, he has no way to know that god did not turn it into a donkey, which was at that moment pissing on all his other books. I'll search for that quote, because it was pretty exciting for a medieval philosophy class.

The point is not to rationalize. God could 2 + 2 = 5 and stop trying to understand His will as it is arbitrary. And then of course use this narrative to legitimize some autocrat.
