What is the ruling on four married daughters demanding the division of their sick, bedridden father's salary, which his only son has been withdrawing for ten years with the father's permission, while the eldest sister claims that the father is incapacitated and semi-deceased, and that the brother is not allowed to dispose of the money alone?

The question contained two points: the ruling on a father benefiting from his salary while bedridden, and the ruling on a son seizing his father's salary.

If the salary is due to retirement or granted by a specific entity, there is no harm in the father benefiting from it. However, if it is due to covering the entity's workers or for any reason not approved by the granting entity, then it is consuming wealth unlawfully and is forbidden.

Regarding a son seizing his father's salary, if the father is in a state of legal incompetence, all his financial dispositions are invalid. The Sharia court must appoint a guardian over his wealth to be spent in his best interest or on his obligatory expenses. The son does not have the right to dispose of his father's wealth, nor do the daughters have the right to inherit from him as long as he is alive.
