What is the ruling on subscribing to an additional pension plan offered by a company, which involves deducting a percentage of the salary and depositing it into a bank account to invest part of it in a life insurance policy and another part in bank investments, with restrictions on withdrawal before ten years?

It is not permissible to subscribe to the additional plan, whether the money deducted is from salary or a grant, because the money is deposited in usurious banks. Depositing in usurious banks is forbidden, even if the usurious interest is disposed of. Furthermore, commercial insurance is forbidden, and it is not permissible to benefit from the insurance amount except in cases of compulsion. In such a case, the sin is lifted, and it becomes permissible to benefit from what the company has paid or what has been deducted from the salary.
