The obligation set rotation between spouses

وَإِنِ ٱمْرَأَةٌ خَافَتْ مِنۢ بَعْلِهَا نُشُوزًا أَوْ إِعْرَاضًۭا فَلَا جُنَاحَ عَلَيْهِمَآ أَن يُصْلِحَا بَيْنَهُمَا صُلْحًۭا ۚ وَٱلصُّلْحُ خَيْرٌۭ ۗ وَأُحْضِرَتِ ٱلْأَنفُسُ ٱلشُّحَّ ۚ وَإِن تُحْسِنُوا۟ وَتَتَّقُوا۟ فَإِنَّ ٱللَّهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًۭا

If a wife fears cruelty or desertion on her husband's part, there is no blame on them if they arrange an amicable settlement between themselves; and such settlement is best; even though men's souls are swayed by greed. But if ye do good and practise self-restraint, Allah is well-acquainted with all that ye do.

وَلَن تَسْتَطِيعُوٓا۟ أَن تَعْدِلُوا۟ بَيْنَ ٱلنِّسَآءِ وَلَوْ حَرَصْتُمْ ۖ فَلَا تَمِيلُوا۟ كُلَّ ٱلْمَيْلِ فَتَذَرُوهَا كَٱلْمُعَلَّقَةِ ۚ وَإِن تُصْلِحُوا۟ وَتَتَّقُوا۟ فَإِنَّ ٱللَّهَ كَانَ غَفُورًۭا رَّحِيمًۭا

Ye are never able to be fair and just as between women, even if it is your ardent desire: But turn not away (from a woman) altogether, so as to leave her (as it were) hanging (in the air). If ye come to a friendly understanding, and practise self-restraint, Allah is Oft-forgiving, Most Merciful.

۞ تُرْجِى مَن تَشَآءُ مِنْهُنَّ وَتُـْٔوِىٓ إِلَيْكَ مَن تَشَآءُ ۖ وَمَنِ ٱبْتَغَيْتَ مِمَّنْ عَزَلْتَ فَلَا جُنَاحَ عَلَيْكَ ۚ ذَٰلِكَ أَدْنَىٰٓ أَن تَقَرَّ أَعْيُنُهُنَّ وَلَا يَحْزَنَّ وَيَرْضَيْنَ بِمَآ ءَاتَيْتَهُنَّ كُلُّهُنَّ ۚ وَٱللَّهُ يَعْلَمُ مَا فِى قُلُوبِكُمْ ۚ وَكَانَ ٱللَّهُ عَلِيمًا حَلِيمًۭا

Thou mayest defer (the turn of) any of them that thou pleasest, and thou mayest receive any thou pleasest: and there is no blame on thee if thou invite one whose (turn) thou hadst set aside. This were nigher to the cooling of their eyes, the prevention of their grief, and their satisfaction - that of all of them - with that which thou hast to give them: and Allah knows (all) that is in your hearts: and Allah is All-Knowing, Most Forbearing.
