17. Surah Al Isra (The Night Journey), Mecca 50

The Quranic Text & Ali’s translation:

وَأَوْفُوا الْكَيْلَ إِذا كِلْتُمْ وَزِنُواْ بِالقِسْطَاسِ الْمُسْتَقِيمِ...   

17: 35.  Give full measure when ye measure, and weigh with a balance that is straight:

...ذَلِكَ خَيْرٌ وَأَحْسَنُ تَأْوِيلاً ﴿٣٥﴾

that is the most fitting and the most advantageous in the final determination.

Transliteration Wa auful kaila iza_ kiltum wa zinu_ bil qista_sil mustaqim(i), za_lika khairuw wa ahsanu ta'wila_(n).

[ 2221. Giving just measure and weight is not only right in itself but is ultimately to the best advantage of the person who gives it. ]

Pickthall’s translation:

17: 35

Pickthall Fill the measure when ye measure, and weigh with a right balance; that is meet, and better in the end.
