Can he delay Hajj because of problems with his wife?
Question

                I am speaking on behalf of my brother. He is planning to do Hajj this year, but for the following reason he is confused about whether he should do so. Unfortunately he is on bad terms with his wife and they are not living together. He is living with his parents and she is living alone with their son. Since his marital problems remain unresolved-i.e. he has not divorced her and neither are they living happily together, he is unsure whether it is right for him to leave his problems unresolved and do Hajj. Could you please give some advice on the matter.
Praise be to Allah.
    When a Muslim is able to do Hajj, he should hasten to do it, 
    and it is not permissible for him to delay it for no reason, because the 
    Prophet  (peace and blessings of Allaah be upon him) said: “Hasten to do 
    Hajj – i.e., the obligatory Hajj – for none of you knows what will happen to 
    him.” (Narrated by Ahmad, 2721; classed as saheeh by al-Albaani in 
    al-Irwa’, 990). And he  (peace and blessings of Allaah be upon him) 
    said: “Whoever wants to do Hajj, let him hasten to do so.” (Classed as hasan 
    by al-Albaani in Saheeh Abi Dawood, 1524). 
What you have mentioned 
    about your brother’s problems is not a reason for delaying Hajj, because 
    Hajj will not prevent him from dealing with this problem, since it is within 
    his power to try to solve this problem and finish with it before he goes for 
    Hajj. His Hajj may be the means of his problem being solved, because of the 
    help from Allaah it may bring and the blessing (barakah) of Hajj and 
    obedience to Allaah. It may be that he will make du’aa’ during his Hajj with 
    regard to this matter, and Allaah will answer and relieve him of this 
    distress. 

    Moreover, our advice to your brother is that he should not 
    hasten to divorce his wife, rather he should take his time and not rush into 
    anything. For divorce is something that Allaah dislikes. 

    If the problem between him and his wife is because of 
    negligence on her part regarding one of the duties towards Allaah, such as 
    if she neglects to pray or is not chaste, etc, then he has to warn her and 
    remind her about Allaah, and call her to Allaah, and try to guide her to 
    obey Allaah. If she persists in not responding to him, then in that case 
    there is nothing to be gained by keeping her. 

    But if the problem between them is of the common type of 
    problems between spouses, and has to do with differences of opinion 
    concerning day to day life and household matters, etc., then he has to be 
    patient and treat her kindly, and try hard to correct what he thinks is 
    inappropriate. For Allaah says (interpretation of the meaning): 

    “and live with them honourably. If you dislike them, it 
    may be that you dislike a thing and Allaah brings through it a great deal of 
    good”

    [al-Nisa’ 4:19]
The husband has to live 
    with his wife honourably and keep her company in a good way, refraining from 
    harming her, and treating her kindly. Living with her honourably also means 
    putting up with any annoyance that his wife may cause him, and he should 
    remember that he will have a great reward for that from Allaah. 

    A man may dislike his wife, but he keeps her out of obedience 
    to Allaah and treats her kindly, and then Allaah brings about a great deal 
    of good from that. He may be blessed with righteous children from her who 
    will benefit him in this world and in the Hereafter; or his dislike may be 
    taken away and replaced with love, as often happens. 

    The Messenger  (peace and blessings of Allaah be upon 
    him) said: “No believing man should hate a believing woman; if he dislikes 
    one of her characteristics he will be pleased with another.” (Narrated by 
    Muslim, 1469). What this means is that it is not appropriate for a believing 
    man to hate a believing woman, because even if he finds some bad 
    characteristic in her for which he may dislike her, he will find another, 
    praiseworthy, characteristic for which he will love her, such as her being 
    chaste or kind or obedient, or some other good characteristic. The same is 
    true of all people, each person has some good attributes and some bad 
    attributes. As the poet said: 

    “Who is there that is pleasing in all his characteristics? It 
    is enough honour for a man’s faults to be few enough to count.” 

    The wise man is the one who weighs up both the good 
    characteristics and the bad. 

    Your brother should make a lot of du’aa’ in the places and at 
    the times when du’aa’ is especially encouraged, during Hajj and otherwise, 
    asking that Allaah may reconcile him with his wife and create love between 
    their hearts. 
And Allaah knows best. May Allaah bestow 
    blessings and peace upon our Prophet Muhammad.
