Is it permissible for him to take Hajj expenses from his father?
Question

                Can my father pay for me and my wife's Hajj? Or can my father gift me the airfare and expenses for our Hajj? If either way will our hajj be nafil.
Praise be to Allah.There is no 
    reason why a well-wisher should not donate Hajj expenses to someone, and it 
    is not a condition of obligatory or naafil Hajj being valid that it should 
    be paid for with the pilgrim’s own money. 
If this 
    donation is given to a relative, then the reward is greater, and he will 
    have a reward like that of Hajj, in sha Allaah. What your father is going to 
    do, paying the expenses for Hajj for you and your wife, is something that is 
    to be appreciated, and he is included in the words of the verse 
    (interpretation of the meaning): 
“Help you 
    one another in Al‑Birr and At‑Taqwa (virtue, righteousness and piety)”

    [al-Maa’idah 5:2]
There is no 
    difference between the two ways mentioned in the question. If you have not 
    done Hajj before then this Hajj will be the obligatory one, and it will not 
    be naafil just because your father donated the expenses. 
In the 
    answer to question no. 36990, 
    we have quoted a fatwa from the scholars of the Standing Committee 
    concerning this. Please refer to it. 
Your father 
    who is going to donate this money should have performed Hajj already, 
    because the command is addressed to him too. 
It is not 
    right to delay Hajj then appointed help someone else to do Hajj, rather he 
    should hasten to do Hajj himself, then if he has any extra money he may help 
    you to do Hajj. 
In the 
    answer to question no. 36637 
    we have quoted a fatwa from the scholars of the Standing Committee 
    concerning this. Please refer to it. 
One 
    indication that it is permissible to do Hajj with money other than one’s own 
    is the fact that it is permissible to give zakaah to a poor person so that 
    he can do Hajj. This is included in the verse in which Allaah says, listing 
    those who are entitled to zakaah, (interpretation of the meaning): 
“and for 
    Allaah’s Cause”

    [al-Tawbah 9:60]
that 
    includes both jihad and Hajj. 
This has 
    already been explained in the answer to question no.

And Allaah 
    knows best.
