Must a husband provide for his wife and children even if she has filed for Khulʿ and maintenance?

The father is obligated to provide for his young children who have no wealth, according to what is customary, whether their mother is divorced or not. He is also obligated to provide for his wife, unless she is disobedient (nashizah) by withholding his right to enjoyment or leaving his home without his permission and without an excuse. In such a case of disobedience, he is not obligated to provide for her, unless she is pregnant, in which case there is a difference of opinion among scholars regarding the obligation of her maintenance.
