Musnad Ahmad 724:3

'Affan narrated to us, Bishr—meaning Ibn al-Mufaddal—narrated to us, 'Abdullah ibn 'Uthman ibn Khuthaym narrated to us, from Isma'il ibn 'Ubayd ibn Rifa'ah ibn Rafi' al-Zuraqi, from his father, from his grandfather, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Our ally is from us, and our freed slave is from us, and the son of our sister is from us."
