The ruling on performing 'Umrah on behalf of a living person, and taking money in exchange for it?

Question:
May Allah reward you. These are the questions we received. The questioner says: Shaykh, a person asked me to perform 'Umrah on his behalf while he is in his own country, and if I return to my country, he will give me money in exchange for this 'Umrah. Is this action permissible?

Answer:
If this person has not performed the 'Umrah of Islam and is unable to perform 'Umrah himself due to a chronic illness or old age, and it is not expected that he will be able to perform it himself, then there is no harm in appointing someone to perform it on his behalf. If he gives him some money in exchange for his expenses and effort, there is nothing wrong with that. However, if this person has already performed the 'Umrah of Islam, it is not prescribed to perform 'Umrah on behalf of a living person who has already performed the 'Umrah of Islam, just as it is not prescribed to perform Hajj on behalf of someone who has already performed the Hajj of Islam.
Therefore, if he desires to perform 'Umrah, he should come and perform it himself. If he is unable to perform 'Umrah, then nothing is required of him, and praise be to Allah. He should strive in other acts of worship, of which there are many. Yes.
