Musannaf Ibn Abi Shayba 18:414

Abu Bakr narrated to us, he said: Ghundar narrated to us, from Shu'bah, from Jabir, from al-Sha'bi, from Shurayh and Masruq, that they both said regarding the rib and what is similar to it: If it is broken and set without a deformity, they said: "There is in it the physician's fee."
