Explanation:
The Mudarabah banking system is a financial concept that is structured on partnership, wherein one partner is the financier (rabbulma) while the other partner is responsible for the supply of labor and skills (mudarib) for the management of the capital invested in the business. Consequently, the factors of production in this system are, labor, capital and entrepreneurship.
The Mudarabah is of two types:
1. Restricted mudarabah: if the financier states a particular business for which the capital is to be invested in.
2. Unrestricted mudarabah: if the financier permits the fund manager or entrepreneur (mudarib) to invest the capital in any business of choice.

Hence, it's a banking system peculiar to the Islamic world and the contractual partners shares profit and loss based on a pre-defined and agreed ratio.
