Surah An-Nahl Verse 91

وَأَوْفُوا بِعَهْدِ اللَّهِ إِذَا عَاهَدتُّمْ وَلَا تَنقُضُوا الْأَيْمَانَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ اللَّهَ عَلَيْكُمْ كَفِيلًا ۚ إِنَّ اللَّهَ يَعْلَمُ مَا تَفْعَلُونَ

Wa awfoo bi Ahdil laahi izaa 'aahattum wa laa tanqudul aimaana ba'da tawkeedihaa wa qad ja'altumul laaha 'alaikum kafeelaa; innal laaha ya'lamu maa taf'aloon

Translation / The Meaning

And fulfill the covenant of Allah when you have taken it, [O believers], and do not break oaths after their confirmation while you have made Allah, over you, a witness. Indeed, Allah knows what you do.
