Surah An-Nisa Verse 129 - English Translation by Safi Ur Rahman Al Mubarakpuri
Surah An-Nisaوَلَن تَسۡتَطِيعُوٓاْ أَن تَعۡدِلُواْ بَيۡنَ ٱلنِّسَآءِ وَلَوۡ حَرَصۡتُمۡۖ فَلَا تَمِيلُواْ كُلَّ ٱلۡمَيۡلِ فَتَذَرُوهَا كَٱلۡمُعَلَّقَةِۚ وَإِن تُصۡلِحُواْ وَتَتَّقُواْ فَإِنَّ ٱللَّهَ كَانَ غَفُورٗا رَّحِيمٗا
You will never be able to do perfect justice between wives even if it is your ardent desire, so do not incline too much to one of them so as to leave the other hanging. And if you do justice, and do all that is right and have Taqwa, then Allah is Ever Oft-Forgiving, Most Merciful
