What is the right of the Mudarib partner and their percentage, and are they entitled to half the price of the land and clinic, or a percentage of the financier's profit resulting from the increase in the land's price, or compensation for services rendered during the past two years, after the financier partner decided not to proceed with their agreed-upon arrangement?

The aforementioned agreement is not a Mudarabah (definition) (profit-sharing partnership), because Mudarabah relies on the payment of money, not an offer [of property or assets], and it is impermissible if combined with a sale or a partnership. What occurred is an authorization from the financier to the second party to supervise the construction of the building. The second party is entitled to a fair wage (ujrat al-mithl), as estimated by experts, for his work, and has no share in the increase in the value of the land or the clinic. It is advised to gain a deep understanding of contractual rulings before entering into them.
