What is the ruling on one who performs Hajj on behalf of another while he does not pray?

The questioner : In the name of Allah, the Most Gracious, the Most Merciful.
The honorable Shaykh, a bearded man accepts Hajj from people, but he does not pray. What is the validity of the Hajj?

The Shaykh : Yes, the man who does not pray at all, neither in the mosque nor in the house, is a disbeliever and an apostate. He must be called to pray; if he prays, well and good, otherwise he is killed as a disbeliever, because he is an apostate. His Hajj is not valid, even if he performs it on behalf of another, because he is a disbeliever. And Allah the Exalted said: , even though the benefit of their expenditures extends to others, yet they are not accepted from them because of their disbelief. And upon the one who knows that this man is a disbeliever, it is obligatory to make him pay back the money he was given and to perform Hajj in place of this Hajj if it was an individual obligation. If it was voluntary, then he owes nothing; that is, if he wishes, he may appoint someone to perform Hajj on his behalf, or he may perform it himself, or he may not perform it. Yes.
