If a woman offers money to her mahram (a relative one may not marry) to take her on Hajj, but he refuses, is he sinful?

Question : That is, if a woman offers money to her mahram to take her on Hajj, and he refuses, is he sinful?

Answer : The answer is no, he is not sinful. But suppose the mahram has not performed the obligatory Hajj, and she says, "I will give you money to be my mahram and take me on Hajj." Is he required to perform Hajj now because he is able to? Or is he not required to? It is possible that he is required to do so, because he is now able, and no one has a favor to claim over him, and he is taking a wage like a camel. Yes.
