Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Salamah ibn Kuhayl, from Dharr, from Ibn 'Abd al-Rahman ibn Abza, from his father, that a man came to Umar, and Ibn Ja'far mentioned a narration similar to that of al-Hakam, and added: He said: And Salamah doubted, he said: I do not know whether he said in it: the elbows or to the hands. So Umar said: Yes, we appoint you over what you have undertaken.
