Shuayb's (peace be upon him) call and his advice to his people

We sent to Midian their brother Shu'aib. He said: "O my people, worship God; you have no other god but He. So do not give in short measure nor underweigh. I see you are prosperous, but I fear the doom of an overwhelming Day for you.

So, O my people, weigh and measure with justness, and do not withhold things due to men, and do not spread corruption in the land, despoiling it.

That which is left to you by God is better, if you are true believers; yet I am not a warden over you."
