Is it permissible to sell shares that are compulsorily granted by a global company with mixed activities and investments (some of which are prohibited) and benefit from their price, given that these shares cannot be refused or exchanged for cash?

It is not permissible to trade in shares of mixed companies. Therefore, it is not permissible to sell the shares of this company, nor can they be used as wages or gifts. The company's allocation of some of these shares to an employee, even if forced, does not establish his ownership of them according to Sharia. If these mixed shares are an integral part of the salary, then the contract must be annulled and a new contract made with the company in a way that these shares are not included in the basic salary, due to the impermissibility of exchanging them. If they are not part of the basic salary but rather in exchange for a specific achievement, then they must be abandoned or cancelled in the contract. However, if they are merely an incentive and a pure gift, this does not affect the validity of the employment contract.
