Sayyiduna Abu Sarihah Ghafari (may Allah be pleased with him) narrates: Once, the Prophet Muhammad (peace and blessings be upon him) looked towards us from his upper chamber while we were discussing the Day of Judgment. He (peace be upon him) asked: "What are you talking about?" We replied: The Day of Judgment. The Prophet (peace be upon him) said: "The Day of Judgment will not come until ten signs appear: the Dajjal, the smoke, the beast of the earth, the rising of the sun from the west, the descent of Sayyiduna Isa son of Maryam (peace be upon him), the emergence of Gog and Magog, and three sinkings of the earth—one in the west, one in the east, and one in the Arabian Peninsula. After all these, a fire will emerge which will come out from 'Aden' (the narrator is in doubt, perhaps these are the words) or from the pit of 'Aden', and it will drive the people to the place of gathering (Mahshar)."
