What is the ruling regarding the husband's father who thought ill of his son's wife and doubted her conduct because she took a job at the airport to help carry luggage while she was carrying her infant child?

What the husband's father did is bad and stems from his ill-will. Jealousy without suspicion is not liked by Allah. It is a reprehensible act for the husband to believe him without verifying. The wife has done well by her patience, and it is necessary to discuss this calmly with the husband. It is not permissible for a woman to travel without a mahram unless there is a necessity, and from this situation, one realizes the wisdom behind the strictness of this ruling. One must avoid situations of doubt.
