Surah An-Nisa Verse 129 - English Translation by Ali Unal
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 deal between your wives with absolute equality (in respect of love and emotional attachment), however much you may desire to do so. But do not turn away altogether (from any one of them), so as to leave her in a dangling state (uncertain if she has or does not have a husband). If you act righteously (between them) and act in piety (fearful of doing any deliberate wrong to any of them), then surely God is All-Forgiving, All-Compassionate
