Economic guidelines in Islam
Of the two groups of modern economies--market economies and centrally planned economies--market economies use supply and demand to fix prices and upholds the value of private property. The government's function in such environments is primarily is to keep the peace within the society. In Communist societies, the means of production are publicly owned and individuals are supposed to contribute services as their abilities allow. It cannot be said that any economy is at the extreme of no regulation or at the extreme of total regulation.
