Sayyiduna Fadl bin Abbas (may Allah be pleased with him) narrated that on the occasion of the Farewell Pilgrimage, a woman from the tribe of Khath'am came and said, "O Messenger of Allah, the obligation of Hajj that Allah has made upon His servants has reached my elderly father, but he does not have the strength to sit on a mount. So can I perform Hajj on his behalf, and will his Hajj be fulfilled?" The Prophet replied, "Yes."
