Sayyiduna al-Bara' (may Allah be pleased with him) narrates: Not every hadith did we hear from the tongue of the Prophet (peace and blessings be upon him); his (peace and blessings be upon him) Companions would narrate hadith to us on his (peace and blessings be upon him) authority, because we were kept busy tending the camels.
Imam Ahmad recorded it, and its narrators are the narrators of the Sahih.
