SAHIH BUKHARI, BOOK 76 To make the Heart Tender (Ar-Riqaq)
Volume 8, Book 76, Number 513:
Narrated Abu Huraira:
Allah's Apostle said, "The Hour will not be established till the sun rises from the west, and when it rises (from the west) and the people see it, then all of them will believe (in Allah). But that will be the time when 'No good it will do to a soul to believe then. If it believed not before.."' (6.158)
The Hour will be established (so suddenly) that two persons spreading a garment between them will not be able to finish their bargain, nor will they be able to fold it up. The Hour will be established while a man is carrying the milk of his she-camel, but cannot drink it; and the Hour will be established when someone is not able to prepare the tank to water his livestock from it; and the Hour will be established when some of you has raised his food to his mouth but cannot eat it."

Narrated Abu Dharr:
I entered the mosque while Allah's Apostle was sitting there. When the sun had set, the Prophet said, "O Abu Dharr! Do you know where this (sun) goes?" I said, "Allah and His Apostle know best." He said, "It goes and asks permission to prostrate, and it is allowed, and (one day) it, as if being ordered to return whence it came, then it will rise from the west." Then the Prophet recited, "That: "And the sun runs on its fixed course (for a term decreed)," (36.38) as it is recited by 'Abdullah.
