An Nisa’ Ayah 20
وَإِنْ أَرَدتُّمُ ٱسْتِبْدَالَ زَوْجٍ مَّكَانَ زَوْجٍ وَءَاتَيْتُمْ إِحْدَٮٰهُنَّ قِنطَارًا فَلَا تَأْخُذُواْ مِنْهُ شَيْــًٔاۚ أَتَأْخُذُونَهُۥ بُهْتَـٰنًا وَإِثْمًا مُّبِينًا ٢٠
If you desire to replace a wife with another and you have given the former ?even? a stack of gold ?as a dowry?, do not take any of it back. Would you ?still? take it unjustly and very sinfully?
