"Quranic science" blogger, referring to this subject, writes that: Revelation is neither an awareness arising from human intellect nor a knowledge arising from human genius, but it is an instruction from God to the prophet.
The writer of this weblog, pointing to the verses related to this subject, makes an example: Those who don't believe in resurrection told the prophet to bring another Quran or change this one with another. Tell, in response to them, I don't have authority to change. I follow what is revealed to me."
At the end, writer remarks that this is the analysis of revelation from revelation's tongue. It introduces itself in such a way that it is a divine and heavenly instruction revealed to prophet from God and prophet is just a mediator.
Revelation can not be compared with human sciences because it is behind human awareness, not having imperfections and limitations of human knowledge.
