The establishing of the dominion of God on earth, the abolishing of the dominion of man, the taking away of sovereignty from the usurper to revert it to God, and the bringing about of the enforcement of the Divine Law (Shari’ah) and the abolition of man-made laws cannot be achieved only through preaching. Those who have usurped the authority of God and are oppressing God’s creatures are not going to give up their power merely through preaching; if it had been so, the task of establishing God’s religion in the world would have been very easy for the Prophets of God. This is contrary to the evidence from the history of the Prophets and the story of the struggle of the true religion, spread over generations.

In Islam, there is no priesthood, and no intermediary between the creature and The Creator; but every Muslim from the ends of earth or in the paths of the sea has the ability of himself to approach his Lord without priest or minister. Nor again can the Muslim administrator derive his authority from any papacy, or from Heaven; but he derives it solely from the Muslim community. Similarly, he derives his principles of administration from the religious law, which is universal in its understanding and application and before which all men come everywhere as equals.

The Arabs ... realized that ascribing sovereignty only to God meant that the authority would be taken away from the priests, the leaders of tribes, the wealthy and the rulers, and would revert to God. It meant that only God's authority would prevail in the heart and conscience, in matters pertaining to religious observances and in the affairs of life such as business, the distribution of wealth and the dispensation of justice—in short, in the souls and bodies of men. They knew very well that the proclamation, "There is no deity except Allah," was a challenge to that worldly authority which had usurped the greatest attribute of God, namely, sovereignty.
