Can he delay Hajj because his wife is sick?
Question

                My question is regarding what the reasons are for a man to delay his hajj until the following year. my husband is a business man which does carry dept but alhumdulilah it would be covered and sorted out by his business partner if something were to happen to him.
also i am expecting our forth child marshaallah and am due to give birth 6 weeks before hajj begins, i also suffer with a joint problem called spd its in the hips, so my mobility is very limited during pregnancy and anf for a while after giving birth. i do not have family support around me to help the the other children and by my husband going for hajj this year i would find it very hard dealing homelife in his absence. are either of these reasons a valid excuse to delay hajj until 2012?.
Praise be to Allah.
    Firstly: 

    What is obligatory for a Muslim when he has the means is to 
    hasten to perform the obligation of Hajj, because the Prophet (blessings and 
    peace of Allah be upon him) said: “Hasten to do Hajj – i.e. the obligatory 
    Hajj – for one of you does not know what is going to happen to him.” 
    Narrated by Ahmad (2721); classed as saheeh by al-Albaani in al-Irwa’ 
    (990). And he (blessings and peace of Allah be upon him) said: “Whoever 
    wants to do Hajj, let him hasten to do it.” Classed as hasan by al-Albaani 
    in Saheeh Abi Dawood (1524). 

    Secondly: 

    If the wife will be adversely affected by her husband 
    travelling for the obligatory Hajj, in the sense of real harm and not 
    something that is imaginary, then in this case it is permissible for the 
    husband to delay Hajj until the following year, because Allah, may He be 
    exalted, 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]. 

    If he fears for his family, then he cannot afford to go for 
    Hajj. 

    But if the husband can leave with her a woman from among his 
    relatives or a servant to help her, then he has to travel for Hajj, and he 
    may not stay in Makkah for a long time after Hajj. 

    If he is not able to do that and his wife needs him to be 
    with her, then there is nothing wrong with him delaying Hajj, and he is 
    excused. 

    And Allah knows best.
