He is complaining of a problem between his wife and his sisters
Question

                My sisters do not like my wife and are always causing problems. Please advise me: should I cut off ties with my sisters or with my wife?.
Praise be to Allah.Allaah has 
    enjoined upholding of family ties and kind treatment of one's wife. We will 
    never tell you to sever your ties with your sisters or with your wife. 
    Rather we tell you: bring them together and do not make the division worse. 
Love comes 
    from Allaah. He has created causes of love and causes of hate. So you have 
    to look at your relationships and seek out the causes of hate and enmity so 
    that you can remove them. And you should try to bring in the causes of love 
    so as to encourage it. These causes include: greeting with salaam, giving 
    gifts, visiting people when they are sick, helping at times of need, and 
    many other things which Islam tells us strengthen bonds and generate love 
    among people. 
In order to 
    calm both sides down, you also have to remind each of them of Allaah and His 
    warning against gossiping, insulting, slandering and interfering in people’s 
    private affairs. 
Adhering to 
    the limits set by Allaah and giving each party their rights, and respecting 
    the rights of the other party and not belittling them or annoying them, will 
    also guarantee happiness and peace in the house and in your relationships. 
You have to 
    advise your wife and your siblings to treat one another well, and try to 
    remove the problems and disputes that exist between them. If your wife and 
    siblings are living in the same house, there is nothing wrong with you 
    giving your wife her own accommodation, if you cannot reconcile between 
    them. Indeed, this may be a means of removing the disputes between them. 
Our advice 
    to your wife is that she should be friendly towards her husband’s family and 
    treat them kindly as much as she can, without doing anything that is 
    forbidden according to sharee’ah. Respecting her husband’s family will make 
    the relationship between her and her husband remain as good as it can be. 
May Allaah help you all to do that which He loves and which pleases Him. May He guide you to the best of words and deeds and attitudes. 
And Allaah knows best.
