وَءَاتُوا۟ ٱلنِّسَآءَ صَدُقَٰتِهِنَّ نِحْلَةًۭ ۚ فَإِن طِبْنَ لَكُمْ عَن شَىْءٍۢ مِّنْهُ نَفْسًۭا فَكُلُوهُ هَنِيٓـًۭٔا مَّرِيٓـًۭٔا
And give unto the women (whom ye marry) free gift of their marriage portions; but if they of their own accord remit unto you a part thereof, then ye are welcome to absorb it (in your wealth).
