His mother does not like his wife and that has led to him living with her family
Question

                My mother does not like my wife, which has led to me leaving home and living with my wife in her parents’ home. What should I do?.
Praise be to Allah.It is not essential for you 
    to live with your family, rather it may be better for you and your wife and 
    your mother for you to live with your wife outside your parents’ house. In 
    most cases the one who lives with his family – or even close to them – will 
    not have a problem-free life. Wise people who measure things against the 
    standards of sharee’ah and wisdom are very few, especially among women 
    because of the jealousy and competition that exists among them. 
Your living away from your 
    family may set things straight between your mother and your wife. Distance 
    is a bonus in many cases, so there is no need to worry. You may see 
    something as bad and feel distressed because of it, then it turns out to be 
    good. Your mother may begin to miss you and her grandchildren because of 
    your being away from her, and her feelings may change towards your wife if 
    she is out of sight and she only sees her occasionally. This is something 
    that is tried and tested. 
But if you want a solution 
    to the cause of the problem, which is that your mother does not like your 
    wife, you have to look for the reasons why she does not like her and find 
    out what is stopping her from liking her. These may be some of the reasons 
    why your mother does not like your wife: 

    1-Mixing too much with her, which 
    leads to too much talk, and the one who talks too much makes too many slips 
    of the tongue.  

    2-Jealousy of your wife and your 
    love for her. This happens a great deal. You often see the husband’s mother 
    being jealous of her son’s love for his wife and his responding to her 
    wishes, and she thinks that this wife has taken her son from her.

    3-Your wife’s bad treatment of 
    your mother. Some wives do not treat their husbands’ mothers well, so they 
    do not answer their requests or show them respect, which leads to many 
    problems between them. 

    4-Your falling short with regard 
    to your mother’s rights and not paying attention to your wife’s rights. The 
    mother cannot hate her son, rather she tries to pick on something which she 
    things is the cause of the problem, which is his wife, so she hates her.
These are some of the 
    reasons which may make your mother dislike your wife. If you see that all or 
    some of them are applicable in your case, then you must deal with it in a 
    wise and good manner. 
We advise you to take the 
    following steps to create love between your mother and your wife: 
1 – Live apart from your 
    mother, and tell your mother that you are doing this even though you don’t 
    want to, for her sake, so that your mother will not put pressure on herself 
    and make herself ill.
2 – Advise your wife to 
    send a lot of gifts to your mother, whether they are material things such as 
    clothes, food etc, or intangible gifts such as sending salaams and asking 
    after her health. 
3 – Asking wise people whom 
    your mother likes to intervene to change her mind about your wife. In this 
    case outsiders may have a greater influence on the mother than her son and 
    her husband.  
We should point out that as 
    you are no longer living with your mother, you should try find separate 
    accommodation for yourself that is separate from your wife’s family too. 
    Perhaps your moving in with them has deepened the rift between the two 
    sides. Moreover it is not usually a good thing in establishing a marriage 
    and it may have a negative effect on the couple’s life. 
Do not forget to pray to 
    Allaah and ask Him to guide all of you to that which He loves and which 
    pleases Him, and ask Allaah to reconcile everyone and bring them together. 
    And to guide them to the best of words, deeds and attitudes. 
And Allaah is the Source of 
    strength.
