Does the husband's saying to his wife, "You are forbidden to me like the sacredness of my father and my mother," after she said, "By Allah Almighty, I have been forcing myself upon you for a long time unwillingly," constitute a Dhihar that necessitates anything?

Prohibiting one's wife by likening her to a father is not considered ẓihār by the majority of scholars. However, some hold that it necessitates an expiation (kaffārah) similar to breaking an oath (yamīn), while others say that nothing is required of you. As for prohibiting one's wife by likening her to a mother, it is an explicit ẓihār that requires the expiation for ẓihār. It is also advisable to pay the expiation for an oath as a way to avoid scholarly disagreement. Repentance to Allah is obligatory for ẓihār, as it is a reprehensible act and a falsehood (munkar wa zūr).
