Is a son considered undutiful if his mother leaves his home by her own choice after being harmed by his wife, and is the mother entitled to ask him to divorce his wife?

A wife's sharp tongue and her insolence towards her husband's mother are objectionable, and the husband must not condone such behavior. A wife living with her husband's mother is permissible by mutual consent. If the wife refuses, she has the right to a separate dwelling of her own and cannot be compelled to live with her husband's mother. The jurists have agreed that the marital home must be free from the husband's family, with the exception of his non-discerning child, due to the harm caused by the wife sharing her home with others. If the wife has a separate dwelling with a private lock and facilities, she has no objection to the husband's relatives living in the rest of the house, provided none of them harms her. If a man moves his mother from the dwelling where his wife resides to another dwelling to prevent discord, this is not an act of disobedience but rather an act of righteousness. He should honor his mother, seek her forgiveness, and explain the religious ruling to her. It is not the mother's right to order her son to divorce his wife without a valid reason.
