Ash-Shuʿbi said, "Somebody who passed along with your Prophet ﷺ 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 ʿAmr! Who told you this narration?" He replied, "Ibn ʿAbbas."
أَخْبَرَنِي مَنْ مَرَّ مَعَ نَبِيِّكُمْ ﷺ عَلَى قَبْرٍ مَنْبُوذٍ فَأَمَّنَا فَصَفَفْنَا خَلْفَهُ فَقُلْنَا يَا أَبَا عَمْرٍو مَنْ حَدَّثَكَ قَالَ ابْنُ عَبَّاسٍ ؓ
