Respected Muftisaheb, As salaam o laikum
On my retirement from public service my pension payment was delayed for over a year. When the pension was eventually paid ” interest ” was added to the pension amount.
The rules of the pension fund state that should there be a long delay in the payment of the pension due to a technical problem on the part of the pension fund, then it will pay a penalty / interest on the amount of pension outstanding.
I have not requested the penalty / interest payment nor have I signed a contract or obligation to receive it.
Please advise on the Shariah permissibility of this “income”
