Narrator:Ibn ‘Abbās
حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا الشَّيْبَانِيُّ، حَدَّثَنَا الشَّعْبِيُّ، أَخْبَرَنِي مَنْ، رَأَى النَّبِيَّ صلى الله عليه وسلم
وَرَأَى قَبْرًا مُنْتَبِذًا فَصَفَّ أَصْحَابَهُ خَلْفَهُ فَصَلَّى عَلَيْهِ
Ash-Shaibani narrated that:
Ash-Sha'bi said: "I was informed by one who saw the Prophet: He (pbuh) saw a solitary grave, s he lined his Companions (behind him) to pray over it." It was said to him (Ash-Sha'bi): "Who informed you?" He said: "Ibn Abbas."
