وَإِنْ أَرَدتُّمُ اسْتِبْدَالَ زَوْجٍ مَّكَانَ زَوْجٍ وَآتَيْتُمْ إِحْدَاهُنَّ قِنطَارًا فَلَا تَأْخُذُوا مِنْهُ شَيْئًا ۚ أَتَأْخُذُونَهُ بُهْتَانًا وَإِثْمًا مُّبِينًا (20)
(4:20) And if you decide to dispense with a wife in order to take another, do not take away anything of what you might have given the first one, even if you had given her a heap of gold. Would you take it back by slandering her and committing a manifest wrong?
