النحل — An-Nahl Ayat 92
وَلَا تَكُوْنُوْا كَالَّتِيْ نَقَضَتْ غَزْلَهَا مِنْۢ بَعْدِ قُوَّةٍ اَنْكَاثًاۗ تَتَّخِذُوْنَ اَيْمَانَكُمْ دَخَلًا ۢ بَيْنَكُمْ اَنْ تَكُوْنَ اُمَّةٌ هِيَ اَرْبٰى مِنْ اُمَّةٍ ۗاِنَّمَا يَبْلُوْكُمُ اللّٰهُ بِهٖۗ وَلَيُبَيِّنَنَّ لَكُمْ يَوْمَ الْقِيٰمَةِ مَا كُنْتُمْ فِيْهِ تَخْتَلِفُوْنَ
Wa lā takūnū kal-latī naqaḍat gazlahā mim ba‘di quwwatin ankāṡā(n), tattakhiżūna aimānakum dakhalam bainakum an takūna ummatun hiya arbā min ummah(tin), innamā yablūkumullāhu bih(ī), wa layubayyinanna lakum yaumal-qiyāmati mā kuntum fīhi takhtalifūn(a).
"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."
