A study of the jurisprudential rules of money and its implications for the design of the monetary system

Proper circulation of money in the economy causes the dynamism of the economy and the prosperity of production and employment. For proper money circulation, it is necessary to formulate a favorable monetary system.Examining and understanding the rules of money helps to design appropriate monetary arrangements. Money rules are examined at two levels. The first level of rulings in cases where money is a personal asset, should khums be paid? 2. What is the ruling on the treasury and the demand for money motivated by business? Should Zakat be paid?The second level is the review of the trading order, which is about money. What is the ruling on borrowing money? What is the ruling on buying and selling money? What is the ruling on renting money?The results of this research, which is obtained by observing the opinions of lawyers and analysis, show. 1. Khums money must be paid. 2. At the discretion of the Islamic ruler, money can be subject to zakat tax on money. First, its obligations must be met, and second, it must not disturb the economic system. 4. Money rent is not allowed.With a comprehensive approach to the laws of money, two principles are achieved for the monetary system: First, it is not desirable to keep money and get out of the trading circuit. Second, "Money should not have an independent market (from the real sector)." These two principles can have good implications for designing a monetary system. Two of the most important of these concepts are: 1. The development of the use of debt reduction contracts (where the real sector is related to the monetary sector). 2. Imposition of heavy taxes on treasures and withdrawal of money from the trading circuit.
