Is it permissible for a wife to refuse to sleep on the floor if her husband orders her to do so during a dispute?

The Shariah has enjoined good companionship between spouses, and each of them must know the rights of the other. A husband insulting his wife is bad behavior. It is advisable to be patient with the husband, advise him gently and kindly, and supplicate for his guidance. If he does not stop, he can be threatened with informing your family.
