Is it permissible for family members to take a portion of the house rent money paid by the father to spend on their needs, and to provide clothing and other necessities?

If you received maintenance from the husband's father, you are permitted to dispose of it for your necessary clothing and furniture, because maintenance becomes your property upon receipt. The jurists have mentioned the permissibility for a woman to dispose of her maintenance through charity or by giving it as a gift, as long as this does not cause her harm.
