وَ اَوْفُوْا بِعَہْدِ اللہِ اِذَا عٰہَدْتُّمْ وَلَا تَـنْقُضُوا الْاَيْمَانَ بَعْدَ تَوْكِيْدِہَا وَقَدْ جَعَلْتُمُ اللہَ عَلَيْكُمْ كَفِيْلًا۰ۭ اِنَّ اللہَ يَعْلَمُ مَا تَفْعَلُوْنَ۹۱
Waawfoo biAAahdi Allahi itha AAahadtum wala tanqudoo alaymana baAAda tawkeediha waqad jaAAaltumu Allaha AAalaykum kafeelan inna Allaha yaAAlamu ma tafAAaloona
Fulfil your covenant with God, having made the covenant, and do not break your oaths once you have sworn them, as you have made God a witness over you. Indeed God knows what you do.
