What is the ruling on one who performs Hajj on behalf of another person in exchange for a sum of money, and who strives to do this every year?

Question:
May Allah reward you. This questioner says: Some people, when they perform Hajj for themselves, also perform Hajj on behalf of others in exchange for a sum of money that covers the cost of Hajj. However, he strives to perform Hajj on behalf of others for money every year, and he rarely performs Hajj for himself. What is the ruling on that?

Answer:
If he performs Hajj for himself, he has fulfilled the obligatory duty, and it is permissible for him to act as a substitute for another. He may take the money to help him with the cost of Hajj and his expenses. However, if he takes it in place of performing Hajj and performs Hajj for the sake of the money, then he has no Hajj; he has no Hajj if his intention is to take the money. But if his intention is Hajj and worship, and he takes the money to help him with the cost of Hajj, then there is no harm in that. Yes.
