(You Shall Keep Your Word)
You shall fulfill your covenant with God when you make such a covenant. You shall not violate the oaths after swearing (by God) to carry them out, for you have made God a guarantor for you. God knows everything you do.
وَأَوفوا بِعَهدِ اللَّهِ إِذا عٰهَدتُم وَلا تَنقُضُوا الأَيمٰنَ بَعدَ تَوكيدِها وَقَد جَعَلتُمُ اللَّهَ عَلَيكُم كَفيلًا إِنَّ اللَّهَ يَعلَمُ ما تَفعَلونَ
