Ahmad (18779) narrated it from Fadl bin Dukayn, who said, Sharik narrated to us, from Abu Jafar Farra, who said, I heard Abu Umaya Fazari, and he mentioned it. This is how it appears in Musnad Ahmad, "Abu Umaya Fazari," though most sources have it as "Abu Aamina Fazari." Tabarani also narrated it in Al-Kabir (22/360) through the route of Israil bin Yunus bin Abu Ishaq Subayi, from Abu Jafar Farra, and he mentioned it.This contains a corroboration of Sharik, who is Ibn Abdullah the judge, known for poor memory, but this corroboration shows that he did not err in this hadith.
