Taking money in return for doing Hajj on behalf of another
Question

                My husband (may Allaah have mercy on him) passed away, and I want to delegate someone to do Hajj on his behalf this year. Is it correct for the one who does Hajj on his behalf to accept money for his efforts apart from the money that he will take for transportation, food and drink, or not?.
Praise be to Allah.
    It is permissible for the one who is appointed to do Hajj on 
    behalf of someone else to take the money that is given to him in return for 
    doing that Hajj, even if it is more than what he spends on transportation, 
    food and drink, and other things that he needs in order to perform Hajj. It 
    is recommended that he intend to earn reward from Allaah for that and do 
    whatever acts of worship that Allaah enables him to do in al-Haram 
    al-Shareef (on his own behalf), and not just do it for the money. 

    And Allaah is the Source of strength.
