"Christianity would be powerless to block this trend because it exists only in the realm of the spirit--"like a vision in a pure ideal world." Islam, on the other hand, is "a complete system" with laws, social codes, economic rules, and its own method of government. Only Islam offered a formula for creating a just and godly society. Thus the real struggle would eventually show itself: It was not a battle between capitalism and communism; it was between Islam and materialism. And inevitably Islam would prevail."
