All the Prophets عليهم السلام came from Allah with the same Message:
"Worship Allah alone and do not set up partners with Him".
“And we sent Nūh to his people, so he said to them: O my people worship Allāh, you have nothing worthy of worship other than Him. Indeed I fear for you the punishment of a severe day.”[7:59]
