Surah Mutaffifin...
“But when they give by measure or weight to men, they cause loss (give less than what is due)." 4. “Do they not think that they shall be raised (to life again)?" 5. "For a Great Day” 6. “The Day when (all) mankind shall stand before the Lord of the Worlds?" The Occasion of Revelation Ibn-Abbas says that when the Prophet (S) arrived in Medina large group of tradesmen used to deal fraudulently, then Allah sent down these verses and, thereafter, they did not commit further fraud.
Another tradition says that: a large number of the inhabitants of Medina were tradesmen at that time. They used to deal fraudulently and many of their dealings were religiously unlawful. Then, these verses were revealed and the Prophet (S) recited them to the citizens of Medina. He also added: ''There are five for five.” They asked him which 'five' were for which ‘five'.
And he answered: “No nation broke their promise but that Allah set their enemies over them.” “No society passed Judgement without suffering excessive poverty when they were heedless of the laws of Allah." ''No nation fornicated without being faced with abundant fatality" “No sect committed fraud save those whose crops became rotted and famine plagued them.” ''No community refused paying Alms tax except that they were parched by draught.” [^3] The late Tabarsi has cited about the occasion of revelation of these verses that there was a man in Medina by the name of Abu -Jahinah who had two scales for measuring: one of them was big, which he used when he wanted to buy things, and the other was small, which was used when he used to sell things.
(Then, this Surah was revealed and warned him and the likes of him).[^4] Woe to Those Who Deal in Fraud In these verses, before everything, it addresses the shortchangers and says: “Woe to the defrauders” This is a threat, indeed, from Allah to these arrogant, unmanly oppressors who tread on the rights of the people.
