Musnad Ahmad 7:9

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from Jami‘ ibn Shaddad, from ‘Amir ibn ‘Abdullah ibn al-Zubayr, from his father, who said: I said to al-Zubayr: "What is the matter with me that I do not hear you narrating from the Messenger of Allah, may Allah bless him and grant him peace, as I hear Ibn Mas‘ud, and so-and-so, and so-and-so?" He said: "As for me, I have not parted from him since I accepted Islam, but I heard a statement from him: 'Whoever lies about me intentionally, let him take his seat in the Fire.'"
