(56) باب سُنَّةِ الصَّلاَةِ عَلَى الْجَنَائِزِ
Narrated Ash-Shaibani:
Ash-Shu`bi said, "Somebody who passed along with your Prophet (p.b.u.h) 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 `Amr! Who told you this narration?" He replied, "Ibn `Abbas."
