A man died without performing Hajj and bequeathed that Hajj be performed on his behalf; is this valid?

Question: A man died without fulfilling the obligatory Hajj and bequeathed that Hajj be performed on his behalf from his wealth. He asks about the validity of the proxy Hajj, and whether the Hajj performed by another is like his own Hajj for himself?

Answer: If a Muslim dies without having performed the obligatory Hajj, while being in a state of fulfilling its conditions of obligation, it is obligatory for someone to perform Hajj on his behalf from the wealth he left behind, whether he made a bequest to that effect or not. If someone else who is qualified to perform Hajj does so on his behalf, and that person has already fulfilled the obligation of Hajj for himself, then his Hajj is valid and suffices to discharge the obligation of Hajj from the deceased, just as if he had performed it for himself. As for whether the reward is less or more, that is up to Allah (Glorified and Exalted is He), for He is the Knower of the conditions and intentions of His servants. There is no doubt that it is obligatory for him to hasten to perform Hajj when he is able to do so before he dies, based on the scriptural evidence indicating this, and he should fear the sin of delaying it.
