Ruling on one who sends his parents for Hajj when he has not done Hajj for himself
Question

                What is the ruling on one who sends his parents for Hajj when he has not done Hajj for himself?.
Praise be to Allah.If a person is able to do 
    Hajj and meets its conditions, then it is obligatory for him to do Hajj that 
    year, and it is not permissible for him to delay Hajj for the sake of his 
    parents or anyone else, because Hajj is obligatory immediately according to 
    the more correct of the two scholarly opinions, and an individual obligation 
    takes precedence over honouring one’s parents.  Allaah says (interpretation 
    of the meaning): 
“And Hajj (pilgrimage to 
    Makkah) to the House (Ka‘bah) is a duty that mankind owes to Allaah, those 
    who can afford the expenses (for one’s conveyance, provision and residence); 
    and whoever disbelieves [i.e. denies Hajj (pilgrimage to Makkah), then he is 
    a disbeliever of Allaah], then Allaah stands not in need of any of the 
    ‘Aalameen (mankind, jinn and all that exists)”
[Aal ‘Imraan 3:97]
And the Prophet  (peace 
    and blessings of Allaah be upon him) said: “Hasten to go out to Makkah, for 
    one of you does not know what he will face of sickness or need.” Narrated by 
    Abu Na’eem in al-Hilyah and by al-Bayhaqi in Shu’ab al-Eemaan; 
    classed as hasan by al-Albaani in Saheeh al-Jaami’ (3990).

But the parents’ Hajj in 
    this case is valid, and this son should hasten to do Hajj when he is able 
    for it. 
The scholars of the 
    Standing Committee for Issuing Fatwas were asked: Is it permissible for a 
    man to send his parents for Hajj before he goes for Hajj himself? 
They replied: Hajj is 
    obligatory for every free, adult Muslim of sound mind who is able to perform 
    it, once in a lifetime. Honouring one’s parents and helping them to do this 
    duty is something that is prescribed as much as one is able to. But you 
    should do Hajj for yourself first, then help your parents if it is not 
    possible for you all to do Hajj together. But if you send your parents for 
    Hajj first, their Hajj is still valid. And Allaah is the Source of strength.
