أَوْفُ وا۟ ٱلْ كَيْلَ وَ لَا تَكُونُ وا۟ مِنَ ٱلْ مُخْسِرِينَ
Give full measure and do not be of those who cause loss.

وَ أَقِيمُ وا۟ ٱلْ وَزْنَ بِ ٱلْ قِسْطِ وَ لَا تُخْسِرُ وا۟ ٱلْ مِيزَانَ
And establish weight in justice and do not make deficient the balance.
83:3
وَ إِذَا كَالُ و هُمْ أَو وَّزَنُ و هُمْ يُخْسِرُ ونَ
But if they give by measure or by weight to them, they cause loss.
