An-Nisa' (The Women)
Surah 4 · Verse 20
And if you intend to exchange one wife in the place of another and if you have given one of them (even) a treasure, then do not take (back) anything from it. Would you take it (back) by slander (A false report to injure someones reputation) and manifest sin?
“That which is given to a wife should not be taken back even if she is divorced.”
