Is it permissible for a mother to conceal her salary and her deceased husband's salary, and not disclose them, especially if it is known that the inheritance must be divided among the children after the mother lives a long life?

There is no blame upon a mother for not informing her children of the wealth or income she possesses. She is not obligated to disclose the amount of her retirement pension or the social security benefits she receives as a gift from the state. She has the right to dispose of her money as long as she is of sound mind. If she gifts something to one of her children, she must or it is recommended that she give a similar amount to the rest of her children. However, if the social security benefit results from the financial rights of the deceased father, it is part of his inheritance and must be distributed among all heirs according to their prescribed shares, and it is not permissible for the mother to claim it exclusively without the consent of the other heirs. Children must honor their mother and treat her kindly, for her right is great, and honoring her is among the most obligatory duties, while disobeying her is among the gravest sins.
