Ash-Shaibani narrated that Ash-Sha'bi said:
"Someone who saw the Prophet pass by an isolated grave told me that he offered the funeral prayer there and his Companions formed rows behind him." It was said: "Who told you this?" He said: "Ibn 'Abbas."
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا هُشَيْمٌ، قَالَ الشَّيْبَانِيُّ أَنْبَأَنَا عَنِ الشَّعْبِيِّ، قَالَ أَخْبَرَنِي مَنْ، رَأَى النَّبِيَّ صلى الله عليه وسلم مَرَّ بِقَبْرٍ مُنْتَبِذٍ، فَصَلَّى عَلَيْهِ وَصَفَّ أَصْحَابَهُ خَلْفَهُ . قِيلَ : مَنْ حَدَّثَكَ قَالَ : ابْنُ عَبَّاسٍ .
