Al-Mujaadila 58:2

As for those among you who divorce their wives by likening them to their mothers[2], they are not their mothers; their mothers are none but those who gave birth to them. They utter words that are abhorrent and false, but Allah is Most Pardoning, Most Forgiving.

[2] By saying to one's wife, "You are to me like the back of my mother," meaning unlawful to approach, which was abolished by the revelation of these verses.

Those who pronounce ẓihār[1639] among you [to separate] from their wives - they are not [consequently] their mothers. Their mothers are none but those who gave birth to them. And indeed, they are saying an objectionable statement and a falsehood. But indeed, Allāh is Pardoning and Forgiving.

[1639] The saying by a husband to his wife, "You are to me like the back of my mother," meaning unlawful to approach. This was a type of divorce practiced by the Arabs before the prophethood of Muḥammad (ﷺ).

2. Those among you who make their wives unlawful to them by (Zihâr الظهار)[1] (i.e. by saying to them "You are like my mother’s back,") they cannot be their mothers. None can be their mothers except those who gave them birth. And verily, they utter an ill word and a lie. And verily, Allâh is Oft-Pardoning, Oft-Forgiving.

[1] (V.58:2) Az-Zihâr الظهار is the saying of a husband to his wife: You are to me like the back of my mother (i.e. unlawful for me to approach).

Such of you as put away your wives (by saying they are as their mothers) - They are not their mothers; none are their mothers except those who gave them birth - they indeed utter an ill word and a lie. And lo! Allah is Forgiving, Merciful.
