Quran 11:84 — Hud (Hud)

To Midyan we sent their brother Shu‘aib. He said, "O my people, worship GOD; you have no other god beside Him. Do not cheat when you measure or weigh. I see that you are prosperous, and I fear for you the retribution of an overwhelming day.

[11:83] Such rocks were designated by your Lord to strike the transgressors.

[11:85] "O my people, you shall give full measure and full weight, equitably. Do not cheat the people out of their rights, and do not roam the earth corruptingly.
