Malaysia and Pakistan have are categories of principle. This principle is profit and loss sharing.
PROFIT AND LOSS SHARING (PLS) is the method utilized in Islamic banking to comply with the prohibition of interest. The Islamic solution, commonly referred to as Profit & Loss Sharing (PLS), suggests an equitable sharing of risks and profits between the parties involved in a financial transaction.

In the banking business, there are three parties - the entrepreneur or the actual user of capital, the bank which serves as a partial user of capital funds and as a financial intermediary, and the depositors in the bank who are the suppliers of savings or capital funds.
There are two different partnerships of the type mentioned in Islam: the partnership between the depositors and the bank, and the partnership between the entrepreneur (or the borrower) and the bank and then, financial institutions will not receive a fixed rate of interest on their outstanding loans, rather, they share in profits or in losses of the business owner to whom they have provided the funds. Similarly, those individuals who deposit their funds in a bank will share in the profit and loss of the financial institution.
For the profit and loss sharing in Malaysia is a mudharabah and musharakah.
This is a kind of partnership where one partner gives money to another for investing in a commercial enterprise. The investment comes from the first partner who is called "Rab-ul-Maal" while the management and work is an exclusive responsibility of the other, who is called "Mudarib" and the profits generated are shared in a predetermined ratio. * The profit will be shared between the two parties according to the terms of the agreement * The losses will be borne by the capital provider alone who is the financier.

Musharakah
Musharakah means a relationship established under a contract by the mutual consent of the parties for sharing of profits and losses in the joint business. It is an agreement under which the Islamic bank provides funds, which are mixed with the funds of the business enterprise and others. All providers of capital are entitled to participate in management, but not necessarily required to do so. The profit is distributed among the partners in pre-agreed ratios, while the loss is borne by each partner strictly in proportion to respective capital contributions.

For the profit and loss sharing in Pakistan same with the Malaysia but different in the name of term such as modarabah certificate rent sharing and the mushrika equity participation and purchase of share. Meanwhile Malaysia is a mudharabah and musharakah term .
