Accept, without the slightest doubt or skepticism, every piece of truth, knowledge and guidance that the Quraan conveys to you. You have every right to enquire, reflect and understand what it contains; but what you cannot fully comprehend is not necessarily unreasonable. You have a right to reject that it is the word of Allah; but once you have accepted it as His, you have no basis whatsoever to doubt even a single word of it. There must be a total surrender and abandonment to the Quraan. Your own opinion, beliefs, notions, whims and caprices should not be allowed to override any part of it.
