بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ
In the name of Allah, Most Gracious, Most Merciful.
16:91
وَأَوْفُوا۟ بِعَهْدِ ٱللَّهِ إِذَا عَـٰهَدتُّمْ وَلَا تَنقُضُوا۟ ٱلْأَيْمَـٰنَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ ٱللَّهَ عَلَيْكُمْ كَفِيلًا ۚ إِنَّ ٱللَّهَ يَعْلَمُ مَا تَفْعَلُونَ
16:91
And fulfill the covenants (taken in the Name of) Allah when you have taken them, and do not break the oaths after you have confirmed them - and indeed you have appointed Allah as your guarantor. Verily, Allah knows what you do. - Safi-ur-Rahman al-Mubarakpuri (English)
