The key to avoiding this endless dissatisfaction is to satisfy ourselves about standards first; to satisfy ourselves that such and such are a list of criteria that constitute proof, satisfying proof, and then we test the subjects that we examine. In particular I will apply this to the Qur'an.

Ask a thoughtful Christian why he is Christian, and he will usually reply, "The miracle of Resurrection." The basis for his belief being that about two thousand years ago a man died and he was raised from the dead. That is his miracle, his 'touchstone', because all else depends on that.

Ask a Muslim, "Well, what is your miracle? Why are you a Muslim? Where is your miracle?" and the Muslim can go over and take his miracle off the shelf and hand it over to you because his miracle is still with us today. It is the Qur'an; it is his 'touchstone'.
