4:20
وَإِنْ أَرَدتُّمُ ٱسْتِبْدَالَ زَوْجٍ مَّكَانَ زَوْجٍ وَءَاتَيْتُمْ إِحْدَىٰهُنَّ قِنطَارًا فَلَا تَأْخُذُوا۟ مِنْهُ شَيْـًٔا ۚ أَتَأْخُذُونَهُۥ بُهْتَـٰنًا وَإِثْمًا مُّبِينًا
4:20
But if you intend to replace a wife by another and you have given one of them a Cantar (of gold i.e. a great amount) as Mahr, take not the least bit of it back; would you take it wrongfully without a right and (with) a manifest sin? - Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan (English)
