Musnad Ahmad 22:27

'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from Sulayman ibn Yasar, from Ibn 'Abbas: Al-Fadl ibn 'Abbas narrated to me, he said: A woman from Khath'am came and said: "O Messenger of Allah, the obligation of Allah, the Almighty and Majestic, regarding Hajj has reached my father, and he is a very old man who cannot remain steady upon his mount." He said: "Then perform Hajj on behalf of your father."
