Her family forbade her to speak to her friend because of her relationship with her friend’s brother, then she got married; can she speak to her now?
Question

                When I was in school, I committed a sin and made friends with a boy who was my friend’s brother, but she had nothing to do with it and she was innocent of my sin. When my family found out about it, they forbade me to talk to her. Now I have got married; is it permissible for me to talk to her, knowing that if I talk to her we will talk about ordinary things that have nothing to do with that boy? May Allaah reward you with good.
Praise be to Allah.If your talking to your 
    friend will not result in any negative consequences such as her brother 
    trying to talk to you or contact you and the like, then there is nothing 
    wrong with your talking to her, because that ban was only because of 
    negative consequences that might result from it. But it should be limited 
    only to talking to her, and not visiting her. It is better if it is done 
    with your family’s knowledge; perhaps they know something that you do not. 
    Keeping company with some people may lead to damaging one’s reputation or 
    being thought badly of, and news of that relationship may reach the 
    husband. 
May Allaah help us and you 
    to do that which He loves and which pleases Him, and divert fitnah 
    (temptation, trouble), both apparent and hidden, away from us. 
And Allaah knows best.
