Musnad Ahmad 22:28

'Abd al-Razzaq narrated to us, Ibn Jurayj narrated to us, 'Amr ibn Dinar informed me, that Ibn 'Abbas used to report that al-Fadl ibn 'Abbas informed him: "That he entered the House (the Ka'bah) with the Prophet, peace and blessings of Allah be upon him, and that the Prophet, peace and blessings of Allah be upon him, did not pray in the House when he entered it. But when he came out and descended, he prayed two rak'ahs at the door of the House."
