Quran 58:2 — The Debate (Al-Mujaadalah)

Those among you who estrange their wives (by declaring them as forbidden in sex) as their mothers know full well that they are not their mothers. Their mothers are the women who gave birth to them. Indeed, they are committing a blasphemy and a falsehood. GOD is Pardoner, Forgiver.

[58:1] GOD has heard the woman who debated with you about her husband, and complained to GOD. GOD heard everything the two of you discussed. GOD is Hearer, Seer.

[58:3] Those who estrange their wives in this manner, then reconcile thereafter, shall atone by freeing a slave before resuming their sexual relations. This is to enlighten you. GOD is Cognizant of everything you do.
