Surah Al Isra Tafseer

وَأَوْفُوا الْكَيْلَ إِذا كِلْتُمْ

And give full measure when you measure.

meaning, do not try to make it weigh less nor wrong people with their belongings.

وَزِنُواْ بِالقِسْطَاسِ

and weigh with a balance,

meaning scales,

الْمُسْتَقِيمِ

that is straight.

meaning that which is not distorted nor that which will cause confusion.

ذَلِكَ خَيْرٌ

that is good,

for you, in your daily life and in your Hereafter.

So Allah says:

وَأَحْسَنُ تَأْوِيلً

and better in the end.

meaning, with regard to your ultimate end in the Hereafter.

ذَلِكَ خَيْرٌ وَأَحْسَنُ تَأْوِيلً

That is good (advantageous) and better in the end.

Sa`id narrated that Qatadah said that this means

"Better in reward and a better end."

Ibn Abbas used to say:

"O people, you are entrusted with two things for which the people who came before you were destroyed - these

weights and

measures."
