Is it permissible for a son to leave his mother's house and care for his wife, despite his mother's disapproval and threat to disown him, in the event that the mother mistreats and wrongs the wife?

The rights of the mother are immense, and showing her kindness is among the most obligatory duties. The mother's differing treatment does not diminish her rights nor does it permit mistreating her; rather, she should be advised gently. The wife has the right to an independent dwelling where she is not subjected to harm, and she is not obliged to serve the husband's mother. If the wife requests an independent dwelling, it must be provided for her, even if the mother refuses. The matter should be handled wisely by honoring the mother and treating the wife well, such as living near the mother to care for her.
