Performing Hajj on behalf of someone without taking money

Q: Since I know for certain that performance of the obligation of Hajj requires effort and money, I authorized someone to perform Hajj on behalf of my mother. I gave him a sum of money so that he can spend out of it, but this person told me that he works for one of the pilgrims' guides and thus does not need to spend any money from the time of his going to perform Hajj until he completes it and comes back. I endeavored to make him understand that Hajj will not be acceptable unless the money is spent. But he insisted on not taking it. Then, I convinced him to accept the money as a gift and he consented to this after a long discussion. He traveled and performed the obligation of Hajj and came back safely by the will of Allah. However, when he returned, he gave me the money back saying that during his stay in Al-Muzdalifah, (Part No. 10; Page No. 57) he was informed that this sum which he received as a gift will deprive him of his personal reward from Allah for performing the obligation of Hajj. He then got angry with me because he thought that I knew beforehand that his acceptance of the money will deprive him of Allah's reward, since he received the worldly reward (i.e. the sum). This embarrassed me very much. I know that spending one's money for making Hajj is a condition. I want to give him this sum in any form whether it is in the form of a gift or expression of gratitude and appreciation of his person. I beg Your Eminence to furnish me with a way I can give him this sum without depriving him of Allah's reward for him for performing this obligation on behalf of my mother.

A: If this person you authorized to perform Hajj on behalf of your mother has performed the rituals of Hajj with the intention of doing them on her behalf, his Hajj on her behalf is valid. Both of you will be rewarded for this and your mother will receive the reward of Hajj In Sha’a-Allah (if Allah wills), whether he received the money you paid him or not. If he refused to take the money out of altruism and seeking the reward (from Allah), this will increase his reward and make his Hajj more acceptable.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and his Companions.
