He has an internet café and is asking about his income
Question

                I am a young Muslim man, praise be to Allaah. I have a shop for internet access, and I do not know whether everything that I earn from it is dubious or not. Please note that I want to get married and do Hajj using this money, in sha Allaah.
Praise be to Allah.If it is 
    possible to control what happens in the internet café and prevent evil, 
    there is nothing wrong with opening it and the income that results from that 
    is halaal. But if it is not possible to control it and the customers use it 
    for things that Allaah has forbidden, such as looking at haraam things and 
    doing evil things – as is the case with most such cafes and their customers 
    – then it is not permissible to open it and the income that results from it 
    is haraam. In that case you have to change the place to another project in 
    which there is no sin and you can earn a halaal income from it, which will 
    help you to worship Allaah by going for Hajj, getting married, etc.

The Standing 
    Committee for Issuing Fatwas was asked a detailed question about internet 
    cafes, which we will quote here: 
Question: 
    There is a lot of talk nowadays about Internet cafes which have become 
    widespread recently. What is the ruling on investing and dealing in these 
    cafes? Knowing that there are some harmful and haraam things, as follows: 
1 – The user 
    rents a computer by the hour, although we do not know what the user is going 
    to use the internet for. There are many programs and sites which the user 
    can access, some of which are beneficial and some are harmful. There are 
    some sites which the King ‘Abd al-‘Azeez Science and Technology City can 
    control and block, but there are some users who are able to enter the 
    forbidden sites anyway. 
Please note 
    that we cannot control the programs except by cancelling the service. 
2 – There is 
    a program called Microsoft Chat, which is for chatting and corresponding, 
    through which users can exchange bad language and foul talk, and they can 
    send and receive pornographic pictures and movies. It is possible to control 
    the sending and receiving of pictures and movies, but there are some people 
    who can break these controls in devious ways. 
Answer: If 
    this equipment can be used for false and evil ends, which will harm Islamic 
    beliefs or enable people to look at permissive pictures and movies, or news 
    of immoral entertainment, or to have dubious conversations and play haraam 
    games, and the owner of the café cannot prevent these evils or control the 
    machines, then in that case it is haraam for him to deal in that, because 
    this is helping in sin and haraam things, and Allaah, may He be glorified 
    and exalted, says in His holy Book (interpretation of the meaning): 
“Help you 
    one another in Al‑Birr and At‑Taqwa (virtue, righteousness and piety); but 
    do not help one another in sin and transgression. And fear Allaah. Verily, 
    Allaah is Severe in punishment”

    [al-Maa'idah 5:2]
And Allaah 
    is the Source of strength. End quote from Fataawa al-Lajnah al-Daa’imah
    (26/284) 
And Allaah 
    knows best.
