Can Nafl Hajj be Performed on behalf of Another?

Q: Hajj-30: If a person has no reason for not performing Nafl Hajj himself, will it be valid if another person performs the Nafl Hajj on his behalf?

Answer: Since having an excuse not to perform Hajj is not a precondition the case of Nafl Hajj, such a Hajj can be performed on one's behalf even if one is able to do so himself.
