Musnad Ahmad 286:4

'Abd al-Rahman ibn Mahdi narrated to us, Sufyan narrated to us, from Furat, from Abu al-Tufayl, from Hudhayfah ibn Asid al-Ghifari, who said: The Messenger of Allah (peace and blessings of Allah be upon him) looked down upon us from a chamber while we were discussing the Hour. He said: "The Hour will not be established until you see ten signs: the rising of the sun from its place of setting, the smoke, the beast, the emergence of Gog and Magog, the emergence of Jesus son of Mary and the Dajjal, and three landslides: a landslide in the west, a landslide in the east, and a landslide in the Arabian Peninsula. And a fire that emerges from the bottom of Aden, driving—or gathering—the people, staying with them wherever they spend the night, and resting with them wherever they rest during the day."
