Is it permissible to perform 'Umrah on behalf of a living father when it is difficult for the father to travel?

The questioner:
We say: Honorable Shaykh, may Allah grant you success. A man’s father is alive, and this son wants to perform 'Umrah on his behalf. This man is not in the land of the two Holy Sanctuaries and needs to travel to perform 'Umrah. Is it permissible for this son to perform 'Umrah on his behalf? Knowing that the father is able to perform tawaf and all the pillars of 'Umrah?

The Shaykh:
No. If the father has not performed the 'Umrah of Islam, he should come and perform it himself if possible. If it is not possible, he waits until the opportunity arises. If he loses hope of coming and becomes unable to do so, he may appoint a proxy at that time if he is incapacitated. However, as long as he can come, or it is expected that he will come and he is able to perform 'Umrah himself, or Hajj likewise, he waits until the opportunity allows him.
And if he wants to be dutiful to his father, let him work to bring him to perform 'Umrah or perform Hajj. He works to bring him at his own expense, receives him, and lets him perform 'Umrah. This is part of being dutiful to him and helping him in the obedience of Allah, Mighty and Majestic. Yes.

The questioner:
He says: Honorable Shaykh, may Allah grant you success. A man performed 'Umrah.

The Shaykh:
As for the voluntary 'Umrah, there is no need for someone to perform a voluntary 'Umrah on his behalf. This is only in the obligatory case. Proxy is entered in the obligatory case in the case of incapacity, in the case of difficult incapacity. Proxy is entered. As for the voluntary in Hajj and 'Umrah, no, proxy is not entered in it, because this matter has not been reported. What has been reported is only in the obligatory case. Yes.
