16. Nahl · verses 91–92

وَأَوۡفُواْ بِعَهۡدِ ٱللَّهِ إِذَا عَٰهَدتُّمۡ وَلَا تَنقُضُواْ ٱلۡأَيۡمَٰنَ بَعۡدَ تَوۡكِيدِهَا وَقَدۡ جَعَلۡتُمُ ٱللَّهَ عَلَيۡكُمۡ كَفِيلًاۚ إِنَّ ٱللَّهَ يَعۡلَمُ مَا تَفۡعَلُونَ

Waawfoo biAAahdi Allahi itha AAahadtum wala tanqudoo alaymana baAAda tawkeediha waqad jaAAaltumu Allaha AAalaykum kafeelan inna Allaha yaAAlamu ma tafAAaloona

Fulfil the Covenant of Allah when ye have entered into it, and break not your oaths after ye have confirmed them; indeed ye have made Allah your surety; for Allah knoweth all that ye do.

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

Wala takoonoo kaallatee naqadat ghazlaha min baAAdi quwwatin ankathan tattakhithoona aymanakum dakhalan baynakum an takoona ommatun hiya arba min ommatin innama yablookumu Allahu bihi walayubayyinanna lakum yawma alqiyamati ma kuntum feehi takhtalifoona

And be not like a woman who breaks into untwisted strands the yarn which she has spun, after it has become strong. Nor take your oaths to practise deception between yourselves, lest one party should be more numerous than another: for Allah will test you by this; and on the Day of Judgment He will certainly make clear to you (the truth of) that wherein ye disagree.
