What is the ruling on participating in an agricultural project with a fixed amount of money, in exchange for a fixed monthly profit, knowing that there are other participants whose profits from certain basins are included to stabilize the overall profit, and that the project owner receives one-third of the profit in exchange for management and marketing, with an agreement to return the equipment or sell it to him upon termination of the contract?

Mudarabah becomes invalid if the Mudarib (agent) guarantees the capital to its owner, or if the agreement stipulates a fixed profit ratio relative to the capital.

There is no harm in the profit being constant if it is not guaranteed by the Mudarib, but rather results from the method and organization of the investment.

It is permissible to combine the profits of all pools and distribute them equally among the participants, if this is by agreement or established custom, with the profits being divided equally if the capitals are equal, and according to shares if they differ.
