Quran Verses
16-Surah An-Nahl ( The Bees ) 91
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.
وَأَوْفُوا بِعَهْدِ اللَّهِ إِذَا عَاهَدتُّمْ وَلَا تَنقُضُوا الْأَيْمَانَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ اللَّهَ عَلَيْكُمْ كَفِيلًا ۚ إِنَّ اللَّهَ يَعْلَمُ مَا تَفْعَلُونَ
