Sahih al-Bukhari 3199

Muhammad ibn Yusuf narrated to us: Sufyan narrated to us, from al-Aʿmash, from Ibrahim al-Taymi, from his father, from Abu Dharr (may Allah be pleased with him), who said: At sunset, the Prophet (ﷺ) said to Abu Dharr, ‘Do you know where it goes?’ I said, ‘Allah and His Messenger know best.’ He said, ‘It goes until it prostrates beneath the Throne and seeks permission. It is permitted. The time is near when it will prostrate and its prostration will not be accepted; it will seek permission and not be permitted. It will be told, “Return from where you came.” Then it will rise from its setting place. That is His, the Exalted’s, saying: “And the sun runs toward its appointed resting place; that is the decree of the Almighty, the All-Knowing.”’
