When is it permissible to perform Hajj on behalf of a living person?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: My uncle resides in Europe, and he wants to go to Makkah to perform the obligatory Hajj. Yes. He says: My uncle resides in Europe, and he wants to go to Makkah to perform the obligatory Hajj, but he is facing some problems from his government. They accused him of having ties to terrorism, and they investigated him but found no case against him. His question is: Since if he goes to Makkah the accusations will return to him, and he has circumstances that do not allow him to leave his country, is it permissible for me to perform Hajj on his behalf? Knowing that he has the money and the physical ability to perform Hajj?

Answer:
The excuse that permits appointing a proxy for Hajj and 'Umrah is an excuse that is not expected to end, such as old age or a chronic illness. This is the one who appoints someone to perform the obligatory Hajj on his behalf. As for a temporary excuse that is expected to end, he waits, praise be to Allah, he waits. If he is able, he performs Hajj; and if he is not able and Hajj becomes difficult for him, then he appoints a proxy to perform Hajj on his behalf. Yes.
