The last two verses below here are by right God's instead of Moses but they are blured - just like Luqmans teachings to his son in chapter 31. Also there are two more occurances, one with Muhammad in chapter 39 but I can't remember what verse, I think somewhere between verse 50 onward. And the other one is in either chapter 51 or chapter 53.------ 

(Pharaoh) said: Who then is the Lord of you twain, O Moses? (20:49)

He said: Our Lord is He Who gave unto everything its nature, then guided it aright. (20:50)

He said: What then is the state of the generations of old? (20:51)

He said: The knowledge thereof is with my Lord in a Record. My Lord neither erreth nor forgetteth,(20:52)

Who hath appointed the earth as a bed and hath threaded roads for you therein and hath sent down water from the sky and thereby We have brought forth divers kinds of vegetation,(20:53)

(Saying): Eat ye and feed your cattle. Lo! herein verily are portents for men of thought.(20:54)

Thereof We created you, and thereunto We return you, and thence We bring you forth a second time.(20:55)
