It is narrated from Sayyiduna Hudhayfah bin Asid (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The Hour will not be established until ten signs appear: the rising of the sun from the west, the Smoke, the Dajjal and the Beast of the Earth, and three sinkings of the earth: in the west, in the east, and in the Arabian Peninsula, the descent of Isa bin Maryam (peace be upon him), Ya'juj and Ma'juj, and a fire that will come out of the depths of Aden and send the people off towards the place of gathering; it will not leave anyone behind, and it will halt for them along the way", meaning, for their needs.
