وَلَن تَسْتَطِيعُوٓا۟ أَن تَعْدِلُوا۟ بَيْنَ ٱلنِّسَآءِ وَلَوْ حَرَصْتُمْ ۖ فَلَا تَمِيلُوا۟ كُلَّ ٱلْمَيْلِ فَتَذَرُوهَا كَٱلْمُعَلَّقَةِ ۚ وَإِن تُصْلِحُوا۟ وَتَتَّقُوا۟ فَإِنَّ ٱللَّهَ كَانَ غَفُورًۭا رَّحِيمًۭا
Ye will not be able to deal equally between (your) wives, however much ye wish (to do so). But turn not altogether away (from one), leaving her as in suspense. If ye do good and keep from evil, lo! Allah is ever Forgiving, Merciful.
Surah An-Nisaa(4:129)
