The ruling on performing Hajj on behalf of a living person who is unable to do so

Question:
He says: Honorable Shaykh, may Allah grant you success. The questioner says: My mother is advanced in age and is unable to perform the rites of Hajj. Is it permissible for me to perform Hajj on her behalf, or is it necessary for her to perform it herself? Please note that she cannot ride in a bus and can only walk a very short distance; she is suffering from diabetes.

Answer:
If she has already performed the obligatory Hajj, there is no need for someone to perform a voluntary Hajj on her behalf; there is no need for that. However, if she has not yet performed the obligatory Hajj, then if it is possible for her to perform Hajj while being carried, it is obligatory for her to do so. But if she is unable to be carried, like the one who cannot stay mounted on the riding animal as mentioned in the hadith, and she cannot be carried, then someone should perform Hajj on her behalf. She should appoint a proxy to perform Hajj on her behalf. Yes.
