Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الشَّيْبَانِيِّ، عَنِ الشَّعْبِيِّ، قَالَ أَخْبَرَنِي مَنْ، مَرَّ مَعَ نَبِيِّكُمْ صلى الله عليه وسلم عَلَى قَبْرٍ مَنْبُوذٍ فَأَمَّنَا فَصَفَفْنَا خَلْفَهُ. فَقُلْنَا يَا أَبَا عَمْرٍو مَنْ حَدَّثَكَ قَالَ ابْنُ عَبَّاسٍ رضى الله عنهما.
Ash-Shu`bi said, "Somebody who passed along with your Prophet (p.b.u.h) by a grave that was separate from the other graves informed me (saying), "The Prophet (ﷺ) led us (in the prayer) and we aligned behind him." We said, "O Abu `Amr! Who told you this narration?" He replied, "Ibn `Abbas."
