Musnad Ahmad 286:1

Sufyan ibn 'Uyaynah narrated to us, from Furat, from Abu al-Tufayl, from Hudhayfah ibn Asid, who said: The Prophet, may Allah bless him and grant him peace, looked out upon us while we were discussing the Hour. He said: "What are you discussing?" They said: "We are discussing the Hour." He said: "It will not be established until you see ten signs: the smoke, the Dajjal, the beast, the rising of the sun from its place of setting, the descent of 'Isa ibn Maryam, Gog and Magog, and three landslides: a landslide in the East, a landslide in the West, and a landslide in the Arabian Peninsula. The last of that will be a fire that emerges from Yemen, driving the people to their place of gathering." Abu 'Abd al-Rahman said: "A word was omitted."
