Hadith 5468

Abu Dharr told that at sunset God's messenger asked him if he knew where the sun went and that when he replied that God and His messenger knew best he said, "It goes and prostrates itself under the Throne, then asks permission to depart and this is granted; but it will soon prostrate itself and that will not be accepted from it, and will ask permission to depart and that will not be granted. It will be told to go back the way it came, and it will rise in its place of setting." That is the meaning of the words of Him who is exalted, "The sun runs to a determined limit[*]." He said that its determined limit is under the Throne. *Quran, 36:38 (Bukhari and Muslim.)
