The disagreement between spouses regarding the children going with their mother to her family

Question:
He says: I am always in conflict with my wife over our children, because she frequently goes to her family and wants the sons and daughters to go with her, while I want them to stay in the house. What is your opinion?

Answer:
First, the default ruling regarding the authority (qawwamah) over the wife and the children is that it belongs to the husband; this is the default. The wife does not leave her house except with her husband's permission, and the children also do not go out except with their father's permission if he sees that there is no harm in their going out, because he is their guardian. Therefore, it is not permissible for her to take them out without their father's consent, because he fears for them that they might mix with young men or children who are not committed to their religion; he fears for them.
Therefore, it is necessary for their father, who is the one in charge of them and their guardian, to be consulted, and it is not permissible for him to give permission unless there is no harm to them in their going out, either in their religion or their bodies. Yes.
