What is the religious ruling on a mother preventing her daughter from returning to her husband after he expelled her, and on her refusal to allow the husband to drive his pregnant daughter to the hospital? Is the mother considered sinful for this action? And would the daughter be disobedient to her mother if she went with her husband without her knowledge? What should she do about this?

The rights of the mother are great, and honoring her is obligatory. However, if a woman marries, the husband's rights take precedence over those of the parents in case of conflict. The wife is not obligated to obey her parents if they command her to separate from her husband, prevent her from returning to him, or meeting him. If the mother incites her daughter to separate from her husband without a legitimate religious reason, she is sinful. The wife must be wary of surrendering to her family's desire to destroy her home. She must return to her husband and live with him honorably, while continuing to honor her mother in ways that do not conflict with her husband's rights and the stability of her family.
