It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Hasten to perform righteous deeds before six events occur: the rising of the sun from the west, the emergence of the Dajjal, the appearance of smoke, the emergence of the Beast of the earth, the death of a particular person among you, or the general death of all."
