An Nahl, 92 Ayah
16:92
وَلَا تَكُونُواْ كَٱلَّتِي نَقَضَتۡ غَزۡلَهَا مِنۢ بَعۡدِ قُوَّةٍ أَنكَٰثٗا تَتَّخِذُونَ أَيۡمَٰنَكُمۡ دَخَلَۢا بَيۡنَكُمۡ أَن تَكُونَ أُمَّةٌ هِيَ أَرۡبَىٰ مِنۡ أُمَّةٍۚ إِنَّمَا يَبۡلُوكُمُ ٱللَّهُ بِهِۦۚ وَلَيُبَيِّنَنَّ لَكُمۡ يَوۡمَ ٱلۡقِيَٰمَةِ مَا كُنتُمۡ فِيهِ تَخۡتَلِفُونَ ٩٢
Wa Lā Takūnū Kāllatī Naqađat Ghazlahā Min Ba`di Qūwatin 'Ankāthāan Tattakhidhūna 'Aymānakum Dakhalāan Baynakum 'An Takūna 'Ummatun Hiya 'Arbá Min 'Ummatin ۚ 'Innamā Yablūkumu Al-Lahu Bihi ۚ Wa Layubayyinanna Lakum Yawma Al-Qiyāmati Mā Kuntum Fīhi Takhtalifūna
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.
