shanavas real faith cannot come without questioning. God gave us the greatest gift, our brains, so that we could use it. If you believe blindly without asking questions then a)your faith can never be strong as it has no logical basis and b)you have chosen not to use your brain and wasted God's greatest gift.
You cannot say that Quran is true just because you were told so and just because you blindly believe. You must question it and then find it to be true. Otherwise it is all waste. It is equal to saying that I blindly believe that a monster made of bread and cream is encircling the sun and that monster is God, and I just believe it as it has been ordered. Blind faith is stupidity.
