حَدَّثَنَا دَاوُدُ بْنُ رُشَيْدٍ، حَدَّثَنَا الْوَلِيدُ، - يَعْنِي ابْنَ مُسْلِمٍ - عَنْ سَعِيدٍ، - وَهُوَ ابْنُ عَبْدِ الْعَزِيزِ - عَنْ عَطِيَّةَ بْنِ قَيْسٍ، عَنْ قَزْعَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ لَقَدْ كَانَتْ صَلاَةُ الظُّهْرِ تُقَامُ فَيَذْهَبُ الذَّاهِبُ إِلَى الْبَقِيعِ فَيَقْضِي حَاجَتَهُ ثُمَّ يَتَوَضَّأُ ثُمَّ يَأْتِي وَرَسُولُ اللَّهِ صلى الله عليه وسلم فِي الرَّكْعَةِ الأُولَى مِمَّا يُطَوِّلُهَا .
The noon prayer would start and one would go to al-Baqi' and after having relieved himself he would perform ablution and then come, while the Messenger of Allah (ﷺ) would be in the first rak'ah, because he would prolong it so much.
