Performing Hajj on behalf of one person

Q 1: Is it permissible to perform Hajj on behalf of a person, whether they are alive or dead? I have a friend whose father died. Is it permissible to perform Hajj on his behalf? Are both of them going to be rewarded? Can he also perform Hajj on behalf of his mother who is not ill, but she cannot travel by car or airplane? Is it permissible for him to perform Hajj once on behalf of his father, his mother and himself, (Part No. 11; Page No. 58) or does he have to perform a separate Hajj for each of them? Is it permissible at all to perform Hajj on their behalf?

A: It is permissible to perform Hajj on behalf of a deceased person, or one who is still living but unable to. It is impermissible to perform Hajj once on behalf of two persons, as Hajj can be only for one person at a time. The same applies to `Umrah. However, it is permissible to perform Hajj on behalf of a person and `Umrah on behalf of another person in the same year, provided that the proxy has performed Hajj and `Umrah himself.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
