"I entered the Masjid at sunset, and the Prophet ﷺ was sitting. He said: 'O Abu Dharr! Do you know where this(sun) goes?' I said:'Allah and His Messenger know better.' He said: 'Indeed it goes to seek permission to prostrate, so it is permitted. And it is as if it has been said to it: "Rise from whence you came." So it shall rise from its setting place.' Then he recited: 'That is its fixed course."' He said: "That is the recitation of 'Abdulla bim Mas'ud."  

دَخَلْتُ الْمَسْجِدَ حِينَ غَابَتِ الشَّمْسُ وَالنَّبِيُّ ﷺ جَالِسٌ فَقَالَ يَا أَبَا ذَرٍّ أَتَدْرِي أَيْنَ تَذْهَبُ هَذِهِ قَالَ قُلْتُ اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهَا تَذْهَبُ تَسْتَأْذِنُ فِي السُّجُودِ فَيُؤْذَنُ لَهَا وَكَأَنَّهَا قَدْ قِيلَ لَهَا اطْلُعِي مِنْ حَيْثُ جِئْتِ فَتَطْلُعُ مِنْ مَغْرِبِهَا قَالَ ثُمَّ قَرَأَ وَذَلِكَ مُسْتَقَرٌ لَهَا قَالَ وَذَلِكَ قِرَاءَةُ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ
