باب اسْتِحْبَابِ التَّبْكِيرِ بِالْعَصْرِ
Sahih Muslim 621 a

Anas b. Malik reported that the Messenger of Allah (ﷺ) used to pray the afternoon prayer when the sun was high and bright, then one would go off to al-'Awali and get there while the sun was still high. Ibn Qutaiba made no mention of" one would go off to al-'Awali".

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح قَالَ وَحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّهُ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي الْعَصْرَ وَالشَّمْسُ مُرْتَفِعَةٌ حَيَّةٌ فَيَذْهَبُ الذَّاهِبُ إِلَى الْعَوَالِي فَيَأْتِي الْعَوَالِيَ وَالشَّمْسُ مُرْتَفِعَةٌ ‏.‏ وَلَمْ يَذْكُرْ قُتَيْبَةُ فَيَأْتِي الْعَوَالِيَ ‏.‏
