Musnad Ahmad 652:91

Muhammad ibn Ja’far narrated to us, Shu’bah narrated to us, from Mansur, from Dharr, from Yusi’ al-Hadrami, from al-Nu’man ibn Bashir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: And he mentioned the like of it. Thus Shu’bah said the like of it. Abu Abd al-Rahman said: "I was informed that Yusi’ is Yusi’ ibn Ma’dan al-Hadrami."
