The Permissibility of Performing Hajj on Behalf of a Sick Person

A young man who has reached the age of twenty and is suffering from a bleeding disorder—Meaning: he has a wound on his elbow from which blood flows—and he is also lame. He has not performed Hajj, and he wants to perform it this year. What should he do, knowing that he fears the crowd of pilgrims this year might cause him a wound due to his bleeding disorder?
If this young man is able to afford it with his wealth, but is not able to perform it with his body, he should appoint someone to perform Hajj on his behalf;From the hadith of Ibn 'Abbas (may Allah be pleased with them both): (A woman from Khath'am said: O Messenger of Allah, my father has reached the age of old age and is unable to sit firmly on a mount, and the obligation of Allah upon His servants to perform Hajj has come upon him. Should I perform Hajj on his behalf?He said: Yes). If this man is unable to perform Hajj because he is lame, and because if he is wounded in any way his blood does not clot but continues to flow, which is a danger to his life, then he is excused. Due to the lameness and the hardship of the crowding, if he does not perform Hajj, there is no sin on him.

The questioner: And if his recovery is expected?The Shaykh: If his recovery is expected, he should postpone it until Allah heals him.
