Is a wife considered disobedient (nashiz) if she leaves her husband's home after an argument in which he swore he would drag her by her hair to place her at his mother's feet, this being subsequent to her refusal to serve her mother-in-law due to the latter's repeated insults, and his slandering of her honor and reputation among people?

A husband has no right to compel his wife to serve his mother, nor does he have the right to humiliate her for not doing so. Honoring one's mother should not come at the expense of wronging one's wife. The general rule is that a wife should not leave her husband's home without his permission, unless there is a necessity. If her departure is to escape harm, then she is not disobedient (nashiz). Otherwise, she is disobedient. It is advised for the couple to communicate, return home, and live together amicably. If they cannot agree, some righteous individuals should intervene to reconcile them.
