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 }  

I entered the mosque while Messenger of Allah ﷺ was sitting there. When the sun had set, the Prophet ﷺ 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 ﷺ recited, "That: "And the sun runs on its fixed course (for a term decreed)," (36.38) as it is recited by ʿAbdullah.  

دَخَلْتُ الْمَسْجِدَ وَرَسُولُ اللَّهِ ﷺ جَالِسٌ فَلَمَّا غَرَبَتِ الشَّمْسُ قَالَ يَا أَبَا ذَرٍّ هَلْ تَدْرِي أَيْنَ تَذْهَبُ هَذِهِ قَالَ قُلْتُ اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهَا تَذْهَبُ تَسْتَأْذِنُ فِي السُّجُودِ فَيُؤْذَنُ لَهَا وَكَأَنَّهَا قَدْ قِيلَ لَهَا ارْجِعِي مِنْ حَيْثُ جِئْتِ فَتَطْلُعُ مِنْ مَغْرِبِهَا ثُمَّ قَرَأَ {ذَلِكَ مُسْتَقَرٌّ لَهَا} فِي قِرَاءَةِ عَبْدِ اللَّهِ  

I entered the mosque and the Messenger of Allah ﷺ was sitting there. When the sun disappeared (from the sight) he said: O Abu Dharr! Do you know where it goes? He (the narrator) said: Allah and His Apostle know best. He (the Holy Prophet) said. Verily it goes and begs permission, for prostration (to Allah) and the permission is granted to it. Once it would be said: Return to the place whence you came, and then it would rise from its setting place. Then he, after the recitation of 'Abdullah recited it: And that is its appointed term.  

دَخَلْتُ الْمَسْجِدَ وَرَسُولُ اللَّهِ ﷺ جَالِسٌ فَلَمَّا غَابَتِ الشَّمْسُ قَالَ يَا أَبَا ذَرٍّ هَلْ تَدْرِي أَيْنَ تَذْهَبُ هَذِهِ قَالَ قُلْتُ اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهَا تَذْهَبُ فَتَسْتَأْذِنُ فِي السُّجُودِ فَيُؤْذَنُ لَهَا وَكَأَنَّهَا قَدْ قِيلَ لَهَا ارْجِعِي مِنْ حَيْثُ جِئْتِ فَتَطْلُعُ مِنْ مَغْرِبِهَا قَالَ ثُمَّ قَرَأَ فِي قِرَاءَةِ عَبْدِ اللَّهِ وَذَلِكَ مُسْتَقَرٌّ لَهَا  

[Machine] Abu Dharr and I were with the Messenger of Allah ﷺ in the mosque when the sun began to set. He asked Abu Dharr, "Where does the sun go?" I replied, "Allah and His Messenger know best." He said, "Verily, it continues on its path until it prostrates beneath the throne of its Lord. Then, it seeks permission and is allowed to rise again. It is as if it is commanded to return to where it came from, and so it rises from its place. And that is its appointed resting place." Muhammad ﷺ then recited the verse: "And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing." (Quran 36:38)  

أَبُو ذَرٍّ بَيْنَمَا أَنَا مَعَ رَسُولِ اللهِ ﷺ فِي الْمَسْجِدِ حِينَ وَجَبَتِ الشَّمْسُ قَالَ يَا أَبَا ذَرٍّ أَيْنَ تَذْهَبُ الشَّمْسُ؟ قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهَا تَذْهَبُ حَتَّى تَسْجُدَ بَيْنَ يَدَيْ رَبِّهَا ﷻ ثُمَّ تَسْتَأْذِنُ فَيُؤْذَنُ لَهَا وَكَأَنَّهَا قَدْ قِيلَ لَهَا ارْجِعِي مِنْ حَيْثُ جِئْتِ فَتَطْلُعُ مِنْ مَكَانِهَا وَذَلِكَ مُسْتَقَرٌّ لَهَا قَالَ مُحَمَّدٌ ثُمَّ قَرَأَ {وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا} [يس 38]  

[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]  

"تدرى أين تذهب؟ (قال: قلت: الله ورسوله أعلم, قال: ) فإنها تذهب حتى تسجد تحت العرش, فتستأذن فيؤذن لها, ويوشك أن تسجد فلا يقبل منها, وتستأذن فلا يؤذن لها (يقال لها): ارجعى من حيث جئت فتطلع من مغربها فذلك قوله تعالى: {وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا} ".
