"Tenure of property is more of a duty than an actual right of possession. Property in the widest sense is a right that can belong only to society, which in turn receives it as a trust from Allah who is the only true owner of anything. ... 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. ... 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."
