Musnad Abu Ya'la al-Mawsili 154:73

And through the same chain from Ibn Umar, that he said: "Shall I not show you the place from which the Messenger of Allah (ﷺ) said: 'The Beast of the Earth will emerge'?" Then he struck with his staff the fissure that is in al-Safa and said: "And it is possessed of feathers and down. And a third of it will emerge, [covering a distance equal to] the swift horse's gallop for three days and three nights." "And it will pass by them, and they will flee from it to the mosques. Then it will say to them: 'Do you think the mosques will save you from me?' Then it will brand them on their noses, and they will be driven in the marketplaces, and it will say: 'O disbeliever, O believer.'"
