Volume 4, Book 54, Number 421:
Narrated Abu Dhar:
The Prophet asked me at sunset, “Do you know where the sun goes (at the time of sunset)?” I
replied, “Allah and His Apostle know better.” He said, “It goes (i.e. travels) till it prostrates Itself un –
derneath the Throne and takes the permission to rise again, and it is permitted and then (a time will
come when) it will be about to prostrate itself but its prostration will not be accepted, and it will ask
permission to go on its course but it will not be permitted, but it will be ordered to return whence it
has come and so it will rise in the west. And that is the interpretation of the Statement of Allah: “And
the sun Runs its fixed course For a term (decreed). that is The Decree of (Allah) The Exalted in Might,
The All-Knowing.” (36.38)
