It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Perform deeds before six things: the rising of the sun from the west, the Dajjal, the smoke, the beast of the earth, death, and the affair of the common people (i.e., a tribulation that will encompass the people, or an affair in which the common people will become dominant)."
