In Islamic history an event about a necklace of the blessed Fatima-tu-Zahra (a.) is known very well, which she gave to a poor man. The necklace on its way gave food and clothes to a poor, freed a slave and performed several other blessed things before returning to its owner Fatima (a.). Although she had "spent" the necklace, she received it back without any further payment and the necklace on its return way fulfilled several other "payments", like freeing a slave.

Another example is known from the time of Imam Hussain (a.). A few days before the battle of Kerbela, Imam Hussain (a.) gave water to Hurr al-Riyahi and his companions. This water freed Hurr from his jails of falsehood and returned to the Imam (a.) in the hands of Sukayna, who got the water from Hurr's wife at the evening after Aschoora. Imam Hussain had left this world, but the water he gave, came back to him.

These two examples show that the economy of truth works within other principles than our today's economy. Nevertheless it is possible, that even today's economical situation can give signs according to a future of just economy. Today's economy work with money. Any economical work without money seems to be not thinkable. To understand this aspect, at first it has to be asked, what money is? What is money and why is interest [riba] forbidden?

Money today is any good that functions as a medium of exchange that is socially and legally accepted in payment for goods and services and in settlement of debts. Money also serves as a standard of value for measuring the relative worth of different goods and services and as a store of value. One can say that money is a form of standardised certificate of debt.

Person A gives person B any good and person B hands over to person A a standardised certificate of debt for this good, which person A can use in a defined economy. In former times money had its own value. The standardized coins have been produced out of gold or silver, so that the money itself at the same time was a good itself. But today's money is no longer the same as real value. The papers in our hands have no own value.

It is only a standardised certificate of debt and has its value only if there is someone to honour this money with any goods. Nevertheless, it is used as a good itself to get interest [riba]. Interest [riba] is another part of today's world economy.
