Verse 16:92

وَلَا تَكُونُوا۟ كَٱلَّتِى نَقَضَتْ غَزْلَهَا مِنۢ بَعْدِ قُوَّةٍ أَنكَٰثًۭا تَتَّخِذُونَ أَيْمَٰنَكُمْ دَخَلًۢا بَيْنَكُمْ أَن تَكُونَ أُمَّةٌ هِىَ أَرْبَىٰ مِنْ أُمَّةٍ ۚ إِنَّمَا يَبْلُوكُمُ ٱللَّهُ بِهِۦ ۚ وَلَيُبَيِّنَنَّ لَكُمْ يَوْمَ ٱلْقِيَٰمَةِ مَا كُنتُمْ فِيهِ تَخْتَلِفُونَ

And do not be like she who untwisted her spun thread after it was strong [by] taking your oaths as [means of] deceit between you because one community is more plentiful [in number or wealth] than another community. Allah only tries you thereby. And He will surely make clear to you on the Day of Resurrection that over which you used to differ.
