What is the ruling on a wife leaving the house without her husband's permission, especially if he is away from home for a long time due to work circumstances, and when he asks her about the reason for her leaving, she considers it to be an accusation of doubt?

A woman is not permitted to leave her home without her husband's permission, unless there is a legitimate Sharia-compliant reason. This ruling applies whether the husband is present or absent. If he forbids her from leaving, she is not allowed to do so. A woman should not consider her husband's inquiries about her during his travels as a sign of suspicion; rather, she should thank him for his protective jealousy, which indicates his love and concern for their well-being.
