Musnad Ahmad 25:1178

'Affan narrated to us, Wuhayb narrated to us, 'Abdullah ibn 'Uthman ibn Khuthaym narrated to us, from Sa'id ibn Jubayr, from Ibn 'Abbas, that he heard him say: The Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever claims to be the son of someone other than his father, or associates himself with someone other than his own masters, upon him is the curse of Allah, the angels, and all of mankind."
