Surah An-Nahlوَأَوۡفُواْ بِعَهۡدِ ٱللَّهِ إِذَا عَٰهَدتُّمۡ وَلَا تَنقُضُواْ ٱلۡأَيۡمَٰنَ بَعۡدَ تَوۡكِيدِهَا وَقَدۡ جَعَلۡتُمُ ٱللَّهَ عَلَيۡكُمۡ كَفِيلًاۚ إِنَّ ٱللَّهَ يَعۡلَمُ مَا تَفۡعَلُونَ
Keep faith with God when you make a pledge. And you shall not break your oaths after you have sworn them, having made God thereby your surety. God has knowledge of what you do
