Your religion is based on faith. In this way, you will be wanting evidence of Heaven and Hell, which you can never get - that is all based on faith. If you are wanting evidence, then you will start looking for evidence of Allah as well (naudhubillah-may Allah protect us from this), and then your mind will become that of an atheists, who says that "nothing is there until proven" and they can never believe that Allah can be proved. Comprehende?
I do not quite understand you point here. Is Islam not based on faith? Do you have have incontrovertible and irrefutable proof that God exists? If so please let us see it.
Mine is a religion of faith just like that of Abraham who left his own country at the call of God and that action was testimony to his faith. He had no Bible, no Qu'ran, just the call of God. Is your faith different to that of Abraham?
