Are the monthly bonus and pension—provided by an international organization where the pension system is based on deducting 7% from the employee's salary monthly, and the organization pays 14%, and the amount is invested—considered doubtful or unlawful?

The mentioned system is a compensatory contract that involves significant ignorance and excessive gharar (definition) (uncertainty), thus it is unlawful. If participation is optional, it is not permissible. However, if it is compulsory, the participant is entitled to what was deducted from their salary and the permissible profits generated therefrom. They also have the right to own the amount contributed by the authority as a gift, along with its permissible investment profits. Any excess beyond that should be disposed of in charitable causes.
