91وَأَوفوا بِعَهدِ اللَّهِ إِذا عاهَدتُم وَلا تَنقُضُوا الأَيمانَ بَعدَ تَوكيدِها وَقَد جَعَلتُمُ اللَّهَ عَلَيكُم كَفيلًا ۚ إِنَّ اللَّهَ يَعلَمُ ما تَفعَلونَ(Muntakhab)And fulfill the solemn promise if you make one and keep the vow and do not break the. oaths after being ratified and after you have made solemn appeal to Allah in witness thereof; Allah knows all that you do.
