What is the ruling regarding a father's maintenance of his two minor daughters who reside with a disobedient (nashiz) mother, knowing that he covers their expenses and provides them with what suffices them?

The disobedient wife's status does not affect the children's maintenance, as their maintenance is an obligation upon the father to provide equitably, as long as he is able, whether they are under his custody or their mother's custody. The custodian, whether the mother or someone else, has the right to receive the minor's maintenance from the father, and it is not a condition for the children to be present with him to eat and drink. The original right of custody after the separation of the spouses belongs to the mother, unless there is an impediment.
