﴿ وَإِنْ أَرَدتُّمُ ٱسْتِبْدَالَ زَوْجٍۢ مَّكَانَ زَوْجٍۢ وَءَاتَيْتُمْ إِحْدَىٰهُنَّ قِنطَارًۭا فَلَا تَأْخُذُوا۟ مِنْهُ شَيْـًٔا ۚ أَتَأْخُذُونَهُۥ بُهْتَٰنًۭا وَإِثْمًۭا مُّبِينًۭا ﴾
“But if you desire to give up a wife and to take another in her stead, do not take away anything of what you have given the first one, however much it may have been. Would you, perchance, take it away by slandering her and thus committing a manifest sin?”
(And if ye wish to exchange one wife for another) He says: If you wish to marry a woman and divorce one you are already married to, or marry a woman in addition to the one you are already married to (and ye have given unto one of them a sum of money (however great)) a dowry, (take nothing from it) from the dowry. (Would ye take it) the dowry (by the way of calumny) as an unlawful possession (and open wrong?) a clear transgression.
