Am I sinful towards my mother for not forcing my wife to live with her, given that there are problems between my wife and my mother, and my wife's desire for her family to care for her during her pregnancy?

The wife's relationship with her in-laws should be good, and the husband should strive to reconcile his wife and mother, giving everyone their due. The wife is not obligated to stay with the husband's mother except with her consent. It is not her right for the husband to stay with her all day; rather, he should treat her kindly and refer to custom, while balancing the rights of his wife and mother. If the wife needs care, the husband must provide a maid or allow her to stay in her family's home for care. The husband must also mollify his mother and beware of her anger.
