The next in line after the nation of Prophet Noah were the 'Aad. They too did not deny the existence of God, or His being the Ilah but at the same time they too believed in Him as the Rabb to the same extent and in the same sense as had Prophet Nuh's people. And so the points of disagreement between them, and the Prophet sent to them, Hud (peace be on all prophets), were the same too:

And to the Aad (We sent) their brother (that Is kinsman) Hud, who said to them : "O' my people, give your 'ibadah to Allah (because) there is no ilah but He; will yon not fear Him?"...(And) they said: "Have you come to us to make us give all of our 'ibadah to Allah alone, exclusively, and give up those to whom our ancestors used to give theirs?" (Quran 7:65-70)

They said: "If our Rabb had wanted, He would have sent down angels (instead of you, a human like us)". (Quran 41:14)
