“Give full measure... Do not defraud people with the scale and cause loss to them!”
Sayyed Abbas Sadr-Ameli
Fill up the measure, and be not of the cheaters
Al-muntakhab fi tafsir al-Qur'an al-Karim
"Dispense to the full", he said, "the quantity ascertained by measuring if you happen to give or sell by a standard measure and be not of those who serve their purpose and accomplish it by means of fraud, dishonesty and deception"
