The Prophet ﷺ 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 underneath 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)  

قَالَ النَّبِيُّ ﷺ لأَبِي ذَرٍّ حِينَ غَرَبَتِ الشَّمْسُ تَدْرِي أَيْنَ تَذْهَبُ قُلْتُ اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهَا تَذْهَبُ حَتَّى تَسْجُدَ تَحْتَ الْعَرْشِ فَتَسْتَأْذِنَ فَيُؤْذَنَ لَهَا وَيُوشِكُ أَنْ تَسْجُدَ فَلاَ يُقْبَلَ مِنْهَا وَتَسْتَأْذِنَ فَلاَ يُؤْذَنَ لَهَا يُقَالُ لَهَا ارْجِعِي مِنْ حَيْثُ جِئْتِ فَتَطْلُعُ مِنْ مَغْرِبِهَا فَذَلِكَ قَوْلُهُ تَعَالَى {وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا ذَلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ }  

[Machine] I was with the Messenger of Allah ﷺ in the mosque when the sun set. He said, "O Abu Dharr, do you know where the sun goes?" I said, "Allah and His Messenger know best." He said, "Indeed, it goes until it prostrates beneath the Throne of its Lord, then seeks permission to return, and permission is granted to it. It is as if it has been said to it, 'Go back to where you came from,' and so it returns to its rising place. That is its resting place." Then he recited, "And the sun runs [on course] toward its stopping point." (Surah Ya-Sin 36:38)  

كُنْتُ مَعَ رَسُولِ اللهِ ﷺ فِي الْمَسْجِدِ حِينَ وَجَبَتِ الشَّمْسُ فَقَالَ يَا أَبَا ذَرٍّ تَدْرِي أَيْنَ تَذْهَبُ الشَّمْسُ؟ قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهَا تَذْهَبُ حَتَّى تَسْجُدَ بَيْنَ يَدَيْ رَبِّهَا فَتَسْتَأْذِنَ فِي الرُّجُوعِ فَيُؤْذَنَ لَهَا وَكَأَنَّهَا قَدْ قِيلَ لَهَا ارْجِعِي مِنْ حَيْثُ جِئْتِ فَتَرْجِعَ إِلَى مَطْلَعِهَا فَذَلِكَ مُسْتَقَرُّهَا ثُمَّ قَرَأَ {وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا} [يس 38]  

[Machine] I was with the Messenger of Allah ﷺ in the mosque at sunset when he said, "Do you know where the sun sets?" I said, "Allah and His Messenger know best." He said, "It goes and prostrates beneath the Throne of its Lord, and seeks permission to rise again. It will be granted permission and soon it will seek permission, but it will not be granted. It will intercede and request, but when that happens, it will be said to it, 'Return to your place.' That is the meaning of the verse: 'And the sun runs [on course] toward its stopping point.' [Quran 36:38]"  

كُنْتُ مَعَ رَسُولِ اللهِ ﷺ فِي الْمَسْجِدِ عِنْدَ مَغْرِبِ الشَّمْسِ فَقَالَ «أَتَدْرُونَ أَيْنَ تَغْرُبُ الشَّمْسُ؟» قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ تَذْهَبُ حَتَّى تَنْتَهِيَ تَحْتَ الْعَرْشِ عِنْدَ رَبِّهَا ثُمَّ تَسْتَأْذِنُ فَيُؤْذَنُ لَهَا وَيُوشِكُ أَنْ تَسْتَأْذِنَ فَلَا يُؤْذَنَ لَهَا وَتَسْتَشْفِعُ وَتَطْلُبُ فَإِذَا قَالَ ذَلِكَ قِيلَ اطْلُعِي مِنْ مَكَانِكِ فَذَلِكَ قَوْلُهُ {وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا} [يس 38]  

"عَنْ أَبِى ذَرٍّ قَالَ: كُنَّا مَعَ النَّبِىِّ ﷺ في الْمَسْجِد عِنْدَ غُرُوبِ الشَّمْسِ فَقَالَ: أَتَدْرِى أَيْنَ تَغْرُبُ الشَّمْسُ؟ قُلْتُ: الله وَرسُولُه أَعْلَمُ، قَالَ: تَذْهَبُ حَتَّى تَسْجُدَ تَحْتَ الْعَرْشِ عِنْدَ ربِّهَا، وَتَسْتَأذِن في الرُّجُوعِ فَيُؤْذَن لَهَا، وَيُوشِكُ أَنْ تَسْتَأذِنَ فَلَا

يُؤْذَن لَهَا حَتَّى تَسْتَشْفِعَ وَتَطْلُبَ، فَإِذَا طَالَ عَلَيْهَا قِيلَ لَهَا: اطْلُعِى مَكَانَكِ فَذَلِكَ قَوْلُهُ: {وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا ذَلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ}.
