Abdullah bin Ahmad bin Hanbal narrates: My father narrated to me, from Abd al-A'la bin Abd al-A'la, from Yunus bin Ubayd, from Humayd bin Hilal, from Hissan bin Kahil - and his father was a soothsayer in the Jahiliyyah - who said: I entered the mosque during the caliphate of Sayyiduna Uthman (may Allah be pleased with him) and saw an elderly man with white hair and a white beard narrating a hadith from the Messenger of Allah (peace and blessings be upon him) through Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him), and he narrated a similar hadith.
