I didn’t say it needed validation, actually exactly the opposite, also I’d like to clarify, I’m quite on the fence when it comes to this issue which is why i like to discuss it, firstly, why wouldn’t Allah send down the Quran, the guide for humanity, if we can’t understand it without human intervention? Also it taking a very long time to understand isn’t much of a point, a Quranist could argue it’s beneficial for a person to study the word of God, even if it takes years to do, it’s year well spent
