وَأَوْفُوا۟ بِعَهْدِ ٱللَّهِ إِذَا عَـٰهَدتُّمْ وَلَا تَنقُضُوا۟ ٱلْأَيْمَـٰنَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ ٱللَّهَ عَلَيْكُمْ كَفِيلًا ۚ إِنَّ ٱللَّهَ 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
Fulfil any pledge you make in God’s name and do not break oaths after you have sworn them, for you have made God your surety: God knows everything you do.
Fulfill your covenant with God when you have made one, and do not break your oaths after confirming them, when you have made God your guarantor over you. God knows what you do.
