Is the wife sinful for not obeying her husband's command to put his mother's belongings in their bedroom, and for his refusal to sleep with her because of that?

Understanding and respect should prevail between spouses. The husband's guardianship (qawamah) is for management, not for domination. The wife must obey her husband in matters related to marriage and its extensions, and she is not permitted to leave the house except with his permission or out of necessity. The husband should allow his wife to study as long as it does not lead to something forbidden or a dereliction of her duties. If studying was stipulated before the marriage contract, then the condition must be fulfilled. There is no harm for the husband in placing his mother's belongings in the bedroom if it does not infringe upon the wife's privacy. Spouses sleeping in the same room is not obligatory; the husband can sleep in another room. We advise the spouses to lighten matters and avoid sensitivity to prevent problems.
