Is the division of cash profits only applicable in a Mudarabah partnership, or does the division include the growth of capital from the initial paid-in capital, taking into account the growth in the project's value and the efforts of the working party?

The lawful profit for a company is anything that exceeds the capital, not merely the revenues. It is determined either by liquidation or by evaluating the project in cash. Whatever exceeds the capital is the profit distributed between the sukuk holders and the Mudarabah agent according to the terms of the contract.
