I am nonetheless certain that Qur'anic civilization will conquer the world if a group of `Ulama' rise today to call for it in a progressive, open, and scientific manner. This civilization addresses itself to both the heart and reason. It appeals to all men and to all people; no vested interests and no prejudices will be able to prevent their movement toward it. Nor is it required that such `ulama' have any more than a genuine iman, and that they sincerely call men to God. Then will mankind find their happiness in this fraternity in God as they found it in the Prophet's time.

The accomplishments of the period of the Prophet and of that of his immediate successors constitute evidence for my claim, advanced in the preface to this work, that scientific research into the spiritual revolution which Muhammad initiated in this world will guide mankind to the new civilization toward which it has been groping. There is no doubt whatever in this regard. Western men of knowledge object to this claim by deploring the spirit dominating Islamic civilization. On the basis of these objections, they accuse Islam of causing the decay and degradation of the Muslim peoples. The most important of these objections is the claim that the determinism of Islam weakens the will of its people, disables them from participating in the struggle for existence, and brings about their decadence and subjugation. To expose the falsity of this claim and other claims will be the purpose of the second essay in this conclusion.
