Sometimes I wonder how much of people's understanding of the quran and all concepts therein are projections from other sources and not the original meaning. Such sources could be hadith, bible, historical legends, faulty historical "truths", religious and historical fabrications, fairytales...
When I see how drastically the message can change just by aligning some words in the quran with each other through cross reference, I wonder much much or how little we actually have it right.
We have terms like insan, nas, jinn, malaika, "people of the book", "jews & christians", haroot, maroot, gibraeel & mikaeel, dhul qarnain, injeel, kauther, "smokeless fire", salsabeel, kaaba, bakka, msr, isa, iblees, shaytan... etc^etc... that many brave, honest and hard working people are working on to find out what they are.
I wonder how much we THINK we know, but that are actually just assumptions in lack of any better understanding. It is a great leap from sunnism to "quranism".... what sort of leap is it from the "current state" of quranism to a much better understanding?
Sometimes one can find clues and new directions when reading "research" by people of other religions (or atheists). Their goal is not seldom biased... to disprove islam, quran, muhammad, god or similar... but all they write may not be lies and fabrications. Sometimes they would present some inconvenient truth... which would disrupt traditional islam, but perhaps would support the quran. Cannot really give any examples. I've hardly put in any scholarly time into research myself up till now (apart from reading lots of mtrl on this forum, which I find is a marvelous gold mine), but I suspect things are certainly not what they seem... especially in religion.
