Narrated Abu Dharr:Once I was with the Prophet (ﷺ) in the mosque at the time of sunset. The Prophet (ﷺ) said, "O Abu Dharr! Do you know where the sun sets?"

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}"
