وَأَوۡفُواْ ٱلۡكَيۡلَ إِذَا كِلۡتُمۡ وَزِنُواْ بِٱلۡقِسۡطَاسِ ٱلۡمُسۡتَقِيمِۚ ذَٰلِكَ خَيۡرٞ وَأَحۡسَنُ تَأۡوِيلٗا
Waawfoo alkayla itha kiltum wazinoo bialqistasi almustaqeemi thalika khayrun waahsanu taweelan
Give full measure when ye measure, and weigh with a balance that is straight: that is the most fitting and the most advantageous in the final determination.
