Is it permissible to make a partnership or shareholding contract that obliges shareholders to contribute a certain percentage of the profit to a specific charitable cause?

The question presents two scenarios:

The first scenario: The condition is stipulated before the contract, which is permissible. The contracting parties have agreed to give a portion of the profit to a third party as a donation from them, and they are qualified to make such a donation. This is the view of the Maliki school.

The second scenario: Informing the partner of the obligation to donate after the contract has been concluded. This is impermissible unless with their consent, due to the Almighty's saying: ﴿O YOU WHO HAVE BELIEVED, DO NOT CONSUME ONE ANOTHER’S WEALTH UNJUSTLY BUT ONLY [IN LAWFUL] TRADE BY MUTUAL CONSENT FROM YOU﴾.
