Holding back the dowry of his wife

وَإِن طَلَّقْتُمُوهُنَّ مِن قَبْلِ أَن تَمَسُّوهُنَّ وَقَدْ فَرَضْتُمْ لَهُنَّ فَرِيضَةًۭ فَنِصْفُ مَا فَرَضْتُمْ إِلَّآ أَن يَعْفُونَ أَوْ يَعْفُوَا۟ ٱلَّذِى بِيَدِهِۦ عُقْدَةُ ٱلنِّكَاحِ ۚ وَأَن تَعْفُوٓا۟ أَقْرَبُ لِلتَّقْوَىٰ ۚ وَلَا تَنسَوُا۟ ٱلْفَضْلَ بَيْنَكُمْ ۚ إِنَّ ٱللَّهَ بِمَا تَعْمَلُونَ بَصِيرٌ

And if ye divorce them before consummation, but after the fixation of a dower for them, then the half of the dower (Is due to them), unless they remit it or (the man's half) is remitted by him in whose hands is the marriage tie; and the remission (of the man's half) is the nearest to righteousness. And do not forget Liberality between yourselves. For Allah sees well all that ye do.

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.
