وَلا تَكونوا كَالَّتي نَقَضَت غَزلَها مِن بَعدِ قُوَّةٍ أَنكاثًا تَتَّخِذونَ أَيمانَكُم دَخَلًا بَينَكُم أَن تَكونَ أُمَّةٌ هِيَ أَربىٰ مِن أُمَّةٍ ۚ إِنَّما يَبلوكُمُ اللَّهُ بِهِ ۚ وَلَيُبَيِّنَنَّ لَكُم يَومَ القِيامَةِ ما كُنتُم فيهِ تَختَلِفونَ

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.
