The Heights - 7:85
"And We sent to Median their brother Shu´ayb. He said: "O My people, worship Allah. You have no gods besides Him. A clear proof has come to you from your Lord. Measure and weigh exactly. Do not eat the people´s right. Do not make corruption in the earth after it has been leveled. This is better for you if you believe."
Allah commands justice in measuring and weighing:
