Musnad Ahmad 7:24

'Abd al-Rahman ibn Mahdi narrated to us, Shu'bah narrated to us, from Jami' ibn Shaddad, from 'Amir ibn 'Abd Allah ibn al-Zubayr, from his father, who said: I said to my father, al-Zubayr ibn al-'Awwam: "What is the matter with you that you do not narrate from the Messenger of Allah, may Allah bless him and grant him peace?" He said: "I have not parted from him since I accepted Islam, but I heard a statement from him; I heard him say: 'Whoever lies about me, let him occupy his seat in the Fire.'"
