อัลกุรอาน7:85 "And to Midian [we sent] their brother Shuʿayb. He said: 'O my people! serve God, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore give full measure and weight and do not diminish to men their things, and do not make mischief in the land after its reform; this is better for you if you are believers.'"
