Narrated Abu Dharr:

He said, "It goes and prostrates underneath (Allah's) Throne; and that is Allah's Statement:-- 'And the sun runs on its fixed course for a term (decreed). And that is the decree of All-Mighty, the All-Knowing....' (36.38)

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا الأَعْمَشُ، عَنْ إِبْرَاهِيمَ التَّيْمِيِّ، عَنْ أَبِيهِ، عَنْ أَبِي ذَرٍّ ـ رضى الله عنه ـ قَالَ كُنْتُ مَعَ النَّبِيِّ صلى الله عليه وسلم فِي الْمَسْجِدِ عِنْدَ غُرُوبِ الشَّمْسِ فَقَالَ ‏"‏ يَا أَبَا ذَرٍّ أَتَدْرِي أَيْنَ تَغْرُبُ الشَّمْسُ ‏"‏‏.‏ قُلْتُ اللَّهُ وَرَسُولُهُ أَعْلَمُ‏.‏ قَالَ ‏"‏ فَإِنَّهَا تَذْهَبُ حَتَّى تَسْجُدَ تَحْتَ الْعَرْشِ، فَذَلِكَ قَوْلُهُ تَعَالَى ‏{‏وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا ذَلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ‏}‏‏"‏
