What the Book actually calls transgression
Read these together rather than one at a time. Allah commands justice and excellence and forbids oppression. A spouse is to be lived with in what is right. And then three verses that name a specific move: holding a woman in order to hurt her, pressing her over housing to make life difficult, and using a child as leverage. The Qur'an names all three as wrong, by name.
Qur’an and Sunnah
۞إِنَّ ٱللَّهَ يَأۡمُرُ بِٱلۡعَدۡلِ وَٱلۡإِحۡسَٰنِ وَإِيتَآيِٕ ذِي ٱلۡقُرۡبَىٰ وَيَنۡهَىٰ عَنِ ٱلۡفَحۡشَآءِ وَٱلۡمُنكَرِ وَٱلۡبَغۡيِۚ يَعِظُكُمۡ لَعَلَّكُمۡ تَذَكَّرُونَ
God commands justice, doing good, and generosity towards relatives and He forbids what is shameful, blameworthy, and oppressive. He teaches you, so that you may take heed
Qur’an 16:90
ٱلطَّلَٰقُ مَرَّتَانِۖ فَإِمۡسَاكُۢ بِمَعۡرُوفٍ أَوۡ تَسۡرِيحُۢ بِإِحۡسَٰنࣲۗ وَلَا يَحِلُّ لَكُمۡ أَن تَأۡخُذُواْ مِمَّآ ءَاتَيۡتُمُوهُنَّ شَيۡـًٔا إِلَّآ أَن يَخَافَآ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِۖ فَإِنۡ خِفۡتُمۡ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِ فَلَا جُنَاحَ عَلَيۡهِمَا فِيمَا ٱفۡتَدَتۡ بِهِۦۗ تِلۡكَ حُدُودُ ٱللَّهِ فَلَا تَعۡتَدُوهَاۚ وَمَن يَتَعَدَّ حُدُودَ ٱللَّهِ فَأُوْلَٰٓئِكَ هُمُ ٱلظَّٰلِمُونَ
Divorce can happen twice, and [each time] wives either be kept on in an acceptable manner or released in a good way. It is not lawful for you to take back anything that you have given [your wives], except where both fear that they cannot maintain [the marriage] within the bounds set by God: if you [arbiters] suspect that the couple may not be able to do this, then there will be no blame on either of them if the woman opts to give something for her release. These are the bounds set by God: do not overstep them. It is those who overstep God’s bounds who are doing wrong
Qur’an 2:229
وَإِذَا طَلَّقۡتُمُ ٱلنِّسَآءَ فَبَلَغۡنَ أَجَلَهُنَّ فَأَمۡسِكُوهُنَّ بِمَعۡرُوفٍ أَوۡ سَرِّحُوهُنَّ بِمَعۡرُوفࣲۚ وَلَا تُمۡسِكُوهُنَّ ضِرَارࣰ ا لِّتَعۡتَدُواْۚ وَمَن يَفۡعَلۡ ذَٰلِكَ فَقَدۡ ظَلَمَ نَفۡسَهُۥۚ وَلَا تَتَّخِذُوٓاْ ءَايَٰتِ ٱللَّهِ هُزُوࣰ اۚ وَٱذۡكُرُواْ نِعۡمَتَ ٱللَّهِ عَلَيۡكُمۡ وَمَآ أَنزَلَ عَلَيۡكُم مِّنَ ٱلۡكِتَٰبِ وَٱلۡحِكۡمَةِ يَعِظُكُم بِهِۦۚ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ بِكُلِّ شَيۡءٍ عَلِيمࣱ
When you divorce women and they have reached their set time, then either keep or release them in a fair manner. Do not hold on to them with intent to harm them and commit aggression: anyone who does this wrongs himself. Do not make a mockery of God’s revelations; remember the favour He blessed you with, and the Scripture and wisdom He sent to teach you. Be mindful of God and know that He has full knowledge of everything
Qur’an 2:231
۞وَٱلۡوَٰلِدَٰتُ يُرۡضِعۡنَ أَوۡلَٰدَهُنَّ حَوۡلَيۡنِ كَامِلَيۡنِۖ لِمَنۡ أَرَادَ أَن يُتِمَّ ٱلرَّضَاعَةَۚ وَعَلَى ٱلۡمَوۡلُودِ لَهُۥ رِزۡقُهُنَّ وَكِسۡوَتُهُنَّ بِٱلۡمَعۡرُوفِۚ لَا تُكَلَّفُ نَفۡسٌ إِلَّا وُسۡعَهَاۚ لَا تُضَآرَّ وَٰلِدَةُۢ بِوَلَدِهَا وَلَا مَوۡلُودࣱ لَّهُۥ بِوَلَدِهِۦۚ وَعَلَى ٱلۡوَارِثِ مِثۡلُ ذَٰلِكَۗ فَإِنۡ أَرَادَا فِصَالًا عَن تَرَاضࣲ مِّنۡهُمَا وَتَشَاوُرࣲ فَلَا جُنَاحَ عَلَيۡهِمَاۗ وَإِنۡ أَرَدتُّمۡ أَن تَسۡتَرۡضِعُوٓاْ أَوۡلَٰدَكُمۡ فَلَا جُنَاحَ عَلَيۡكُمۡ إِذَا سَلَّمۡتُم مَّآ ءَاتَيۡتُم بِٱلۡمَعۡرُوفِۗ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ بِمَا تَعۡمَلُونَ بَصِيرࣱ
Mothers suckle their children for two whole years, if they wish to complete the term, and clothing and maintenance must be borne by the father in a fair manner. No one should be burdened with more than they can bear: no mother shall be made to suffer harm on account of her child, nor any father on account of his. The same duty is incumbent on the father’s heir. If, by mutual consent and consultation, the couple wish to wean [the child], they will not be blamed, nor will there be any blame if you wish to engage a wet nurse, provided you pay as agreed in a fair manner. Be mindful of God, knowing that He sees everything you do
Qur’an 2:233
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا يَحِلُّ لَكُمۡ أَن تَرِثُواْ ٱلنِّسَآءَ كَرۡهࣰ اۖ وَلَا تَعۡضُلُوهُنَّ لِتَذۡهَبُواْ بِبَعۡضِ مَآ ءَاتَيۡتُمُوهُنَّ إِلَّآ أَن يَأۡتِينَ بِفَٰحِشَةࣲ مُّبَيِّنَةࣲۚ وَعَاشِرُوهُنَّ بِٱلۡمَعۡرُوفِۚ فَإِن كَرِهۡتُمُوهُنَّ فَعَسَىٰٓ أَن تَكۡرَهُواْ شَيۡـࣰٔ ا وَيَجۡعَلَ ٱللَّهُ فِيهِ خَيۡرࣰ ا كَثِيرࣰ ا
You who believe, it is not lawful for you to inherit women against their will, nor should you treat your wives harshly, hoping to take back some of the bride-gift you gave them, unless they are guilty of something clearly outrageous. Live with them in accordance with what is fair and kind: if you dislike them, it may well be that you dislike something in which God has put much good
Qur’an 4:19
أَسۡكِنُوهُنَّ مِنۡ حَيۡثُ سَكَنتُم مِّن وُجۡدِكُمۡ وَلَا تُضَآرُّوهُنَّ لِتُضَيِّقُواْ عَلَيۡهِنَّۚ وَإِن كُنَّ أُوْلَٰتِ حَمۡلࣲ فَأَنفِقُواْ عَلَيۡهِنَّ حَتَّىٰ يَضَعۡنَ حَمۡلَهُنَّۚ فَإِنۡ أَرۡضَعۡنَ لَكُمۡ فَـَٔاتُوهُنَّ أُجُورَهُنَّ وَأۡتَمِرُواْ بَيۡنَكُم بِمَعۡرُوفࣲۖ وَإِن تَعَاسَرۡتُمۡ فَسَتُرۡضِعُ لَهُۥٓ أُخۡرَىٰ
House the wives you are divorcing according to your means, wherever you house yourselves, and do not harass them so as to make their lives difficult. If they are pregnant, maintain them until they are delivered of their burdens; if they suckle your infants, pay them for it. Consult together in a good way- if you make difficulties for one another, another woman may suckle the child for the father––
