Musannaf Ibn Abi Shaybah 39802 — Reports on the death of the Prophet

Ja'far narrates from his father that no imam led the (funeral) prayer over the Prophet (peace and blessings be upon him). Rather, the people would enter (the chamber) to him (peace and blessings be upon him) in groups, offer the funeral prayer over him (peace and blessings be upon him) and come out.
