Is it permissible to accept the financial compensation awarded by the Capital Market Authority due to the bank's delay in processing shares that were erroneously added, resulting in a financial loss?

You have the right to claim not to bear any loss due to the erroneous entry of shares into your portfolio. If the Capital Market Authority rules for compensation, there is no harm in taking it. Compensation is only for material damages; it is impermissible to take it for moral damages, according to the more preponderant opinion.
