Is a husband's defense of his wife in certain situations considered disobedience to parents, especially if it leads to the father's anger, disownment, and an oath of divorce upon the mother to divorce the wife?

The fundamental principle is that a person should not take something owned by another except after seeking their permission. If what the sister took belongs to the wife, then the wife has the right to object and request permission. However, if it belongs to the husband, then the wife was mistaken, and she should have remained silent. The wife should inform her husband about what was taken from him after his sister departs. Informing the husband's brother that it is impermissible for him to stay in his house with his wife in his absence is a necessary right. Insulting the wife by the in-laws is forbidden and impermissible. A father's request to his son to divorce his wife is impermissible, and obedience is not obligatory in this matter. It is advisable to hold onto the wife as long as she possesses religious commitment and good character.
