Al Quran can be tested/verified in many ways. Here are a few things to ponder:
When you buy a self-assembly piece of furniture (e.g. from Ikea) and it comes with instructions, how can you verify the accuracy/truthfulness of those instructions?
Bring a chapter like it? e.g. 10:37-38
Some more [ur=http://www.quran434.com/study-method.htmll]examples[/url]:
21:10, 30:30, 41:53, 51:20-21 - its information and teachings should map to our reality (within our psyche, experience and to the furthest horizons). All signs, internal and external can point to the truth of it and act as a verification mechanism.
29:20, 3:137, 3:190-191, 45:3-4 - knowledge of archaeology/biology/physics/history/sciences/philosophy etc will all help to better understand it.
Blind faith? I don't think so:
6:75-79, 21:57-67, 36:78-79, 21:22, 23:91, 2:258, 12:26-27, 22:5-6, 2:260 - promotes logical thinking.
2:269, 8:22 - strong affinity towards use of wisdom and reason.
49:6, 45:24, 6:116, 53:28, 2:111, 21:24 - disapproves of conjecture/guesswork and promotes examination of evidence.
