Surah An-Nisa Verse 129 - English Translation by Dr Munir Munshey
Surah An-Nisaوَلَن تَسۡتَطِيعُوٓاْ أَن تَعۡدِلُواْ بَيۡنَ ٱلنِّسَآءِ وَلَوۡ حَرَصۡتُمۡۖ فَلَا تَمِيلُواْ كُلَّ ٱلۡمَيۡلِ فَتَذَرُوهَا كَٱلۡمُعَلَّقَةِۚ وَإِن تُصۡلِحُواْ وَتَتَّقُواْ فَإِنَّ ٱللَّهَ كَانَ غَفُورٗا رَّحِيمٗا
Even if you (sincerely) desire (and try), you will not be able to maintain equality among (all) your wives. So do not lean towards one to an extent that you leave others (apprehensive and) in abeyance. If you mend your ways and fear (Allah), then indeed Allah is the most Forgiving and the most Merciful
