Is a sister entitled to claim half of her father's retirement pension that her mother used to receive, based on a law that permits a widow to share her husband's pension with his mother, even though the sister has another income and her children are employed, and she previously received financial assistance from her mother and brother?

The salary disbursed to the deceased's family from the state or company has several scenarios:

1. If it is a right belonging to the deceased: It becomes part of the inheritance and is distributed among the heirs according to their prescribed shares in Islamic law. 2. If it is a gift (hibah): It is allocated to those specified by the granting entity and does not enter into the inheritance. 3. If it is a mixture: Each part follows its own specific ruling.

If the pension was a pure gift and the mother took possession of the sister's share, then the sister's right remains a debt owed by the mother, to be paid from her estate if one exists. The children are not obligated to pay it back except as a voluntary act. However, if the mother had given the daughter her right, then she owes no debt. It is advisable to consult scholars directly for clarification.
