سورة النساء

وَإِنْ أَرَدْتُمُ اسْتِبْدَالَ زَوْجٍ مَكَانَ زَوْجٍ وَآتَيْتُمْ إِحْدَاهُنَّ قِنْطَارًا فَلَا تَأْخُذُوا مِنْهُ شَيْئًا ۚ أَتَأْخُذُونَهُ بُهْتَانًا وَإِثْمًا مُبِينًا ﴿٢٠﴾

Surah an-Nisa'

20. And if you desire to take one wife in place of another, even if you have given one of them a fortune, take nothing back from it. Would you take it back fraudulently and sinfully?
