Is it permissible to dedicate the reward of tawaf or 'Umrah to a living person who is capable of performing the rites himself?

Question:
May Allah reward you. A person performs tawaf voluntarily without performing 'Umrah and dedicates its reward to one of his parents while they are still alive. Is that permissible?

Answer:
It is not reported that one performs 'Umrah on behalf of a living person or Hajj on behalf of a living person, unless the person is unable to fulfill the obligation of Islam, in which case one performs Hajj and 'Umrah on his behalf. However, if he is strong and alive, one does not perform Hajj or 'Umrah on his behalf; rather, he performs Hajj and 'Umrah himself. Yes.
