The descendents of Noah divided the earth among themselves after the death of Noah. From among these descendents were people who disobeyed God, so God send a messenger to them but they rejected him and continued in their sinful ways. So God destroyed them, the two peoples descended from Aram son of Shem son of Noah. One of them was the people of Ad to whom the prophet Hud was sent. The other was the people of Thamud to whom the Prophet Salih was sent.
