قَالُوا۟ نَفْقِدُ صُوَاعَ ٱلْمَلِكِ وَلِمَن جَآءَ بِهِۦ حِمْلُ بَعِيرٍ وَأَنَا۠ بِهِۦ زَعِيمٌ

They replied, ‘The king’s drinking-cup is missing,’ and, ‘Whoever returns it will get a camel-load [of grain],’ and, ‘I give you my word.’

وَأَوْفُوا۟ بِعَهْدِ ٱللَّهِ إِذَا عَـٰهَدتُّمْ وَلَا تَنقُضُوا۟ ٱلْأَيْمَـٰنَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ ٱللَّهَ عَلَيْكُمْ كَفِيلًا ۚ إِنَّ ٱللَّهَ يَعْلَمُ مَا تَفْعَلُونَ

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.
