lbn 'Abbas (RAA) narrated that "Al-Fadl Ibn 'Abbas was riding behind the Messenger of Allah (ﷺ) when a woman from the tribe of Khath"am came along, and al-Fadl started looking at her and she also started looking at him. The Messenger of Allah (ﷺ) kept on turning al-Fadl's face to the other side. She said, "O Messenger of Allah! Allah has prescribed Hajj for His servants, and it has become due on my father who is an old man, who cannot sit stable on his mount. Shall I perform Hajj on his behalf?' The Prophet (ﷺ) replied, "Yes, you may." This incident took place during the Farewell Pilgrimage of the Prophet (ﷺ). Agreed upon, and the wording is from Al·Bukhari'.
