"And to Midian (We sent) their brother Shu'aib. He said: O my people, serve Allah, you have no other god save Him. And give not short measure and weight. I see you in prosperity, and I fear for you the chastisement of an all-encompassing day: And, O my people, give full measure and weight justly, and defraud not men of their things, and act not corruptly in the land, making mischief: What remains with Allah is better for you, if you are believers. And I am not a keeper over you."
