Is there a required expiation (Kaffarah) for equating one's wife to the back of another man?
General Chapter
Al-Mughni
Book of Zihar
Primary text
There are two narrations concerning the requirement of expiation. The first narration dictates that expiation is required because it is a form of prohibition, resembling the situation where one prohibits their own wealth.

The second narration states that no expiation is required. Ibn al-Qasim narrated from Ahmad, concerning one who compares his wife to the back of a man, that it is not Zihar and that nothing is incumbent upon him, as the comparison is made to something not intended for enjoyment, similar to comparing her to another person's wealth.
