Narrated from Hazrat Hudhaifah bin Asid Ghifari (may Allah be pleased with him): He said that the Messenger of Allah (peace and blessings be upon him) looked towards us from his room while we were discussing the Day of Judgment. The Prophet (peace and blessings be upon him) said: "The Hour will not be established until ten signs appear: the Dajjal, the smoke, the rising of the sun from the west, the emergence of the beast from the earth, one sinking of the earth in the east, another sinking in the west, and a third sinking in the Arabian Peninsula, and a fire will emerge from the depths of the earth at the place of Aden which will drive people towards the place of gathering. That fire will stay with them wherever they halt (for rest), and it will rest with them when they rest at noon."
