Payments made by social security to daughters and wives is their exclusive property and the other heirs do not have any share in it

Praise be to Allah.

What is paid by social insurance or social security to the daughters and the wife is their exclusive property, and the other heirs do not have the right to take anything from this money, because it is not part of the estate; rather it is conditional help given by the state, to those who fulfil the conditions of entitlement to this help. The one who is not entitled to this money -- based on the conditions of entitlement -- is not permitted to take any of this money. 

With regard to what the father received during his lifetime, whatever is left of it following his death is to be shared out with the rest of his estate to all the heirs. 

And Allaah knows best.
