Swearing that one's wife will be unlawful for him if she entered her maternal uncle's house, then she went with his consent

Q 5: What is the ruling on a man who swore that his wife would be unlawful for him if she entered her maternal uncle's house, then after some time she went there with his consent?

(Part No. 20; Page No. 295) A: If the husband’s intention when he swore that oath was only to forbid his wife from entering her maternal uncle’s house and she did enter it, he must offer Kaffarah (expiation) for breaking an oath. The Kaffarah is to provide ten needy people with the average food that his family eats, or to provide them with clothing, or to emancipate a believing slave. In case he is unable to carry out any of these, he must observe Sawm (Fast) for three days. On the other hand, if his intention was to declare her unlawful for him as his mother, then he must offer Kaffarah for Zhihar (a man likening his wife to an unmarriageable relative) before he can resume intimacy with her. The Kaffarah for Zhihar is to emancipate a believing slave. In case he cannot find any, he must observe Sawm for two consecutive months. If he is unable to do this, he must feed sixty needy people. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
