Is it permissible to lie to one's mother in order to avoid her resentment towards one's wife and her family? Is the son considered to be undermining his wife's rights if his mother interferes in their lives? And what is the son's Islamic duty towards his wife's family?

It is not obligatory to inform the mother of all details of marital life, and lying is not permissible except in cases of extreme necessity, with a preference for tawriyah (ambiguous speech). It is not legally required to go out for a stroll with the wife, but it is recommended to increase intimacy. It is not obligatory to financially assist the wife's family or to give them gifts, but it is recommended if the husband is able, especially if they are in need, as it involves honoring them and increasing affection. Alternating dinner between the husband's house and the wife's parents' house is not obligatory, and the husband should not be pressured into it. The husband's right takes precedence over the parents' right in case of conflict, and the wife is not considered disobedient if she does not fulfill her parents' wish regarding the alternation; however, it is recommended to deal with them gently. A woman is not permitted to work without her husband's permission unless there was a prior condition, and it is recommended for the husband to permit her to work if it is Islamically regulated and does not harm the family, especially if she is helping her parents.
