(66) باب الصَّلاَةِ عَلَى الْقَبْرِ بَعْدَ مَا يُدْفَنُ
Narrated Sulaiman Ash-Shaibani:
I heard Ash-Shu`bi saying, "I was told by a man who had passed with the Prophet (p.b.u.h) by a grave that was separate from the other graves that he (the Prophet (ﷺ) ) led them in the prayer and they prayed behind him." I said, "O Abu `Amr! Who narrated that to you?" He replied, "Ibn `Abbas."
