What is the Sharia ruling on a wife saying to her husband, while angry, "I will go out with a man more handsome than you, because I hate you"?

This statement does not affect the inviolability of the marital bond, but it is objectionable and丑陋 (ugly/repugnant) because it is a determination to commit a sin and shows disdain for it. It also harms the husband and belittles him. The wife must repent and treat her husband with kindness. The husband, in turn, should explain his rights to her, and if she does not obey him, he should pursue the means of reform with her through admonition, avoidance (boycotting), and non-violent striking.
