7:85And to Median, their brother Shuaib. He said, “O my people, worship God; you have no god other than Him. A clear proof has come to you from your Lord. Give full measure and weight, and do not cheat people out of their rights, and do not corrupt the land once it has been set right. This is better for you, if you are believers.”

7:205And remember your Lord within yourself, humbly and fearfully, and quietly, in the morning and the evening, and do not be of the neglectful.
