What did Ibn 'Abbas tell Sulaiman Ash-Shaibani that the Prophet Muhammad (saw) did while passing by a separate grave?
 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 ) led them in the prayer and they prayed behind him." I said, "O Abu `Amr! Who narrated that to you?" He replied, "Ibn `Abbas."
