لَّا جُنَاحَ عَلَيْكُمْ إِن طَلَّقْتُمُ ٱلنِّسَآءَ مَا لَمْ تَمَسُّوهُنَّ أَوْ تَفْرِضُوا۟ لَهُنَّ فَرِيضَةًۭ ۚ وَمَتِّعُوهُنَّ عَلَى ٱلْمُوسِعِ قَدَرُهُۥ وَعَلَى ٱلْمُقْتِرِ قَدَرُهُۥ مَتَٰعًۢا بِٱلْمَعْرُوفِ ۖ حَقًّا عَلَى ٱلْمُحْسِنِينَ

There is no blame on you if ye divorce women before consummation or the fixation of their dower; but bestow on them (A suitable gift), the wealthy according to his means, and the poor according to his means;- A gift of a reasonable amount is due from those who wish to do the right thing.

وَءَاتُوا۟ ٱلنِّسَآءَ صَدُقَٰتِهِنَّ نِحْلَةًۭ ۚ فَإِن طِبْنَ لَكُمْ عَن شَىْءٍۢ مِّنْهُ نَفْسًۭا فَكُلُوهُ هَنِيٓـًۭٔا مَّرِيٓـًۭٔا

And give the women (on marriage) their dower as a free gift; but if they, of their own good pleasure, remit any part of it to you, Take it and enjoy it with right good cheer.
