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."
Those who are corrected; those who witness the message of Allah, those who are aware:
The Cattle/6:48

The Heights/7:35
O sons of Adam, when messengers come to you from among yourselves and inform you of My Verses, those who listen and correct themselves will have no fear nor will they grieve.
