Hud · 11:84

84. We sent to Madyan their brother, Shu’ayb, who said: O my people, worship Allah alone. You have no other god that deserves to be worshipped besides Him. Do not give people less in the measure of volume and weight when you deal with them. I see you in prosperity and with blessings, so do not change Allah’s favour to you by committing sins. I fear for you the punishment of an encompassing day that will reach every one of you and from which you will not find any place to run to or seek refuge in.
