"The right of disposal depends on being mature and being able to fulfill one's duties; when the possessor does not meet these requirements, then the natural fruits of ownership come to an end."

“It is not the intention of Islam to force its beliefs on people, but Islam is not merely ‘belief’. As we have pointed out, Islam is a declaration of the freedom of man from servitude to other men. Thus it strives from the beginning to abolish all those systems and governments which are based on the rule of man over men and the servitude of one human being to another. When Islam releases people from this political pressure and presents to them its spiritual message, appealing to their reason, it gives them complete freedom to accept or not to accept its beliefs.”

“There can be no real place for personal possession unless it carries with it the rights of disposal and use. The condition on which this right must stand is that of wisdom in the disposal; if the disposal of property is foolish, then the ruler or society may withdraw this right of disposal.”

“Islam chose to unite earth and heaven in a single system, present both in the heart of the individual and the actuality of society, recognizing no separation of practical exertion from religious impulse. ... The center of its being and the field of its action is human life in its entirety, spiritual and material, religious and worldly. Such a religion cannot continue to exist in isolation from society, nor can its adherents be true Muslims unless they practice their faith in their social, legal and economic relationships.”

“Islam's way of life is unique, for in systems other than Islam, some people worship others in some form or another. Only in the Islamic way of life do all men become free from the servitude of some men to others and devote themselves to the worship of God alone, deriving guidance from Him alone, and bowing before him alone.”

“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.”

“Islam knows only two kinds of societies, the Islamic and the Jahili. The Islamic society is that which follows Islam in belief and ways of worship, in law and organization, in morals and manners. The Jahili society is that which does not follow Islam and in which neither the Islamic belief and concepts, nor Islamic values and standards, Islamic laws and regulations, or Islamic morals and manners are cared for.”
