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.

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 prescribes the bases of social justice. It insures that the poor have claims on the possessions of the rich, and it lays down a just policy for government and finance. It does not need to numb people's feelings and does not call on people to abandon their rights on earth and to expect them only in the Kingdom of Heaven.
