Is income from an internet café halaal or haraam?
Question

                I am wondering whether income from an internet café is halaal or haraam, noting that this café is the only source of income for a Muslim family.
Praise be to Allah.
    The internet may be used for both halaal and haraam purposes, 
    for both good and evil. If you can control the place and prevent people from 
    using the internet in haraam ways, then the income that comes from this café 
    is halaal. 

    But if the owner of the café is careless about denouncing 
    evil actions of his customers and he does not prevent them from doing haraam 
    things, then he is a sinner, because he does not denounce evil and he 
    cooperates with them in sin. In that case his income is evil and is haraam. 

    See also question no.
