What is the ruling regarding a wife's refusal to wash and iron clothes and leaving her husband alone during siesta, while the other wife accepts that?

A wife must obey her husband in washing and ironing clothes, as long as it does not cause her undue hardship, because this is part of the wife’s internal service to her husband, and it is obligatory upon her according to custom. As for her leaving her room for her husband to sleep in alone, this is not obligatory. If she does it, it is a favor from her, and it is considered a noble deed and a commendable act of altruism.
