Musnad Ahmad 27:604

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, and Hajjaj said: Shu‘bah narrated to me, from Simak al-Hanafi, who said: I heard Ibn ‘Umar saying: "The Messenger of Allah (ﷺ) prayed inside the House (the Ka‘bah)." And you will come to those who will forbid you from it, so you will listen to them—meaning Ibn ‘Abbas. Hajjaj said: "So you will listen to his statement." Ibn Ja‘far said: And Ibn ‘Abbas was sitting near him.
