Abdullah bin Abbas reported,

A woman from Khathaam asked the Prophet ﷺ on the morning of Muzdalifah, "Messenger of Allah, the obligation of Hajj that Allah has placed upon His servants has reached my father as a very old man who cannot hold himself steady on a mount. May I perform Hajj on his behalf?"He replied, "Yes."
