What is the ruling on relatives continuing to receive a pension for their deceased father without informing the company, knowing that they would only receive a quarter of the salary if they did inform, and that they are in dire need of this money?

The ruling on a deceased father's retirement pension varies depending on its source. If it was a portion of his salary deducted by the employer, then it takes the ruling of an inheritance and is distributed among all heirs, and the company has no right to interfere in its distribution. However, if it is a grant from the company, then the conditions of the granting entity must be adhered to. It is not permissible to conceal the father's death to continue receiving the pension, as this is considered deception and illicitly consuming people's wealth. They must inform the company of their father's death, and whatever they took after his death and before informing the company must be returned, and they must repent to Allah.
