Musnad Ahmad 907:126

Abdullah narrated to us, Muhammad ibn Abi Ghalib narrated to me, ‘Amr ibn Talhah narrated to us, Asbat narrated to us, from Simak, from Jabir ibn Samurah, from the Prophet (peace and blessings of Allah be upon him): "That he prayed behind him on an Eid day without an Adhan and without an Iqamah." And Simak claimed, "That he prayed behind al-Nu’man ibn Bashir and al-Mughirah ibn Shu’bah without an Adhan."
