The rate of interest performs important economic functions.

It brings saving into balance with investment, it rations the available credit, it balances the supply with the demand of money, and it can be used by the monetary authority to manage the economy.

The prohibition of interest in Islam necessitates looking for alternatives which can perform the same functions.

In this work, a model for the rate of return is suggested, the saving function and the investment function were suggested and equilibrium conditions were specified in the long run and the short run.
