وَاَوْفُوْا بِعَهْدِ اللّٰهِ اِذَا عٰهَدْتُّمْ وَلَا تَنْقُضُوا الْاَيْمَانَ بَعْدَ تَوْكِيْدِهَا وَقَدْ جَعَلْتُمُ اللّٰهَ عَلَيْكُمْ كَفِيْلًاؕ اِنَّ اللّٰهَ يَعْلَمُ مَا تَفْعَلُوْنَ ٩١
Translation
Fulfill Allah’s covenant when you pledge, and do not break [your] oaths, after pledging them solemnly and having made Allah a witness over yourselves. Indeed Allah knows what you do.
