Dr. Mustafa Khattab, the Clear Quran - Surah Al-Isra, ayah 35

Translation of Surah Al-Isra, ayah 35 (17:35)

وَأَوۡفُواْ ٱلۡكَيۡلَ إِذَا كِلۡتُمۡ وَزِنُواْ بِٱلۡقِسۡطَاسِ ٱلۡمُسۡتَقِيمِۚ ذَٰلِكَ خَيۡرٞ وَأَحۡسَنُ تَأۡوِيلٗا ٣٥
Give in full when you measure, and weigh with an even balance. That is fairest and best in the end.
