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

“And it will not be within your power to treat your wives with equal fairness, however much you may desire it; and so, do not allow yourselves to incline towards one to the exclusion of the other, leaving her in a state, as it were, of having and not having a husband. But if you put things to rights and are conscious of Him - behold, God is indeed much-forgiving, a dispenser of grace.”

You will never be able to be just to to treat equally your wives in terms of love even if you be eager for this; yet do not turn altogether away towards the one you love with respect to the shares and maintenance expenses so that you leave her the one from whom you turn away like one suspended one that is neither a slavegirl nor a woman with a husband. If you set things right by being just with the shares and fear injustice surely God is ever Forgiving regarding the inclination in your hearts Merciful to you in this respect.
