Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
(1)
Allah's Statement: "And the sun runs on its fixed course for a term (appointed). That is the Decree of the All Mighty, the All-Knowing." (V.36:38)
(1)
Sahih al-Bukhari 4803

Narrated Abu Dharr:

I asked the Prophet (ﷺ) about the Statement of Allah:-- 'And the sun runs on fixed course for a term (decreed), ' (36.38) He said, "Its course is underneath "Allah's Throne." (Prostration of Sun trees, stars. mentioned in Qur'an and Hadith does not mean like our prostration but it means that these objects are obedient to their Creator (Allah) and they obey for what they have been created for).

حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَعْمَشُ، عَنْ إِبْرَاهِيمَ التَّيْمِيِّ، عَنْ أَبِيهِ، عَنْ أَبِي ذَرٍّ، قَالَ سَأَلْتُ النَّبِيَّ صلى الله عليه وسلم عَنْ قَوْلِهِ تَعَالَى ‏{‏وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَهَا‏}‏ قَالَ ‏"‏ مُسْتَقَرُّهَا تَحْتَ الْعَرْشِ ‏"‏‏.‏
