Sahih Muslim Book 041, Number 6931:


Hudhaifa b. Usaid Ghifari reported: Allah's Messenger (may peace be upon him) came to us all of a sudden as we were (busy in a discussion). He said: What do you discuss about? They (the Companions) said. We are discussing about the Last Hour. Thereupon he said: It will not cone until you see ten signs before and (in this connection) he made a mention of the smoke, Dajjal, the beast, the rising of the sun from the west, the descent of Jesus son of Mary (Allah be pleased with him), the Gog and Magog, and land-slidings in three places, one in the east, one in the west and one in Arabia at the end of which fire would burn forth from the Yemen, and would drive people to the place of their assembly.
