Musnad Ahmad 2954

It was narrated that Ibn ‘Abbas (رضي الله عنه) said: The devils had stations in the sky where they would listen to the revelation, and the stars did not move (i.e., there were no shooting stars) and the devils were not targeted. When they heard the revelation they would come down to earth and add nine words to one. When the Prophet (ﷺ) was sent, a devil would sit at the station and shooting stars would come at him and keep after him until they burned him. They complained about that to Iblees who said: This can only be because something has happened. So he sent his troops out in all directions, and they saw the Messenger of Allah (ﷺ) standing and praying between the two mountains of Nakhlah. They went back to Iblees and told him, and he said. This is what has happened.
