He is afraid that he may lose his job and he has some money; does he have to do Hajj with it?
Question

                Next year, if Allah wills, I will possess enough money to perform Hajj alone without my wife. This amount would be sufficient for urgent circumstances; especially that I work in the private sector. The company I work for might ask me to resign at any time. Do I have to perform hajj or not? Bear in mind that I have another amount of money but it is needed for my consummation (we had our marriage contract done but not consummation yet).
Praise be to Allah.
    In order for Hajj to be obligatory for the adult, it is 
    stipulated that he should be financially and physically able for it, because 
    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)”

    [Aal ‘Imraan 3:97]. 

    The fuqaha’ interpreted financial ability as meaning that one 
    has enough to cover food and transportation, i.e., the expenses of travel to 
    and from the Sacred House of Allaah, if this cost is surplus to one’s basic 
    needs and other expenditure as prescribed in sharee’ah, and to pay off his 
    debts. 

    What is meant here by expenditure is that he should have 
    enough to cover his own and his family’s maintenance until he returns, and 
    after he returns he should have enough to suffice him and those on whom he 
    spends, such as the rent on property or salary or trade and so on. Hence he 
    does not have to go for Hajj using the capital of his business, if he spends 
    on himself and his family from its profits, and if taking away from the 
    capital will result in a reduction in profits, such that they will not be 
    enough for him and his family. For more information on this, please see the 
    answer to question no. 11534. 

    If you have the money that will be sufficient for you to do 
    Hajj, and it is surplus to your needs, then you must go for Hajj, unless 
    your fear of losing your job is a real fear based on strong circumstantial 
    evidence, in which case you do not have to do Hajj. But if this fear is just 
    an illusion and notion with no basis, then you have to do Hajj. 

    As for the money that you have set aside for marriage, you do 
    not have to do Hajj with it if you fear hardship for yourself in the event 
    of delaying your marriage, rather you should give precedence to marriage. If 
    there is any other money, you can use that for Hajj, otherwise Hajj is not 
    obligatory for you because you cannot afford it. 

    Ibn Qudaamah (may Allaah have mercy on him) said: If he needs 
    to get married and he fears that it will be too difficult for him otherwise, 
    then he should give priority to that, because it is obligatory for him and 
    he cannot do without it, so it becomes part of his essential spending. But 
    he has no such fears, then he should give priority to Hajj, because marriage 
    is voluntary and should not take precedence over Hajj which is obligatory.
