Is it permissible to perform 'Umrah on behalf of another person if they are alive?

Question:
A sick brother of mine says he is unable to come to Makkah for 'Umrah. Should I perform 'Umrah on his behalf?

Answer:
If he has performed 'Umrah before, then praise be to Allah; he has fulfilled what is required of him. Do not perform a voluntary 'Umrah on his behalf. Do not perform a voluntary 'Umrah on his behalf. You do not enter into representation for a voluntary 'Umrah. That is, there is no evidence that one person performs a voluntary 'Umrah on behalf of another, or performs a voluntary Hajj on behalf of another, while the person is alive. As for the deceased, yes, a person may perform 'Umrah and Hajj on behalf of the deceased, both obligatory and voluntary. But for a living person, one does not perform 'Umrah or Hajj on his behalf as long as he is alive, except in one case: if he has not performed the Hajj of Islam or the 'Umrah of Islam, and he is unable to come, his inability is continuous, and it is not expected that he will be able to do so in the future, and that is not expected of him. In this case, it is permissible to represent him for the obligatory act specifically. As for the voluntary act, no, as long as he is alive, one does not perform 'Umrah or Hajj on his behalf voluntarily, as long as he is alive. Because the hadiths only came regarding representation for the deceased and for the one who is unable to perform the obligatory act while alive.
