Is it obligatory for the wife to obey her husband if he orders her to prevent her sister from giving anything to his daughters?

A wife is not obligated to obey her husband if he forbids his daughters from taking something from their maternal aunt, as this does not pertain to marital rights or the rights of Allah. If the husband has a valid reason, he can forbid his daughters himself. We advise both spouses to fear Allah, avoid discord, adhere to the limits set by Allah, shun injustice, grant rights, and be tolerant.
