Ruling on selling subscriptions to a file downloading site on the Internet
Question

                What is the ruling on selling subscriptions to a file downloading site such as rapidshare, where people upload their files to the site, and in order to download from this site it is necessary to buy a subscription to the site?.
Praise be to Allah.
    File downloading sites on the Internet may be used for good 
    or bad, beneficial or harmful purposes. In cases such as this, one should 
    refer to the principle of buying or renting things that may be used for 
    halaal or haraam purposes: 

    It is permissible to sell subscriptions to those who it is 
    known or thought most likely that they will use it for permissible 
    purposes. 

    And it is haraam to sell them to those whom it is known or 
    thought most likely that they will use it for haraam purposes, such as 
    putting haraam images, indecent movies and so on. 

    If it is not known and the seller is uncertain and does not 
    know whether the buyer will use it for halaal or haraam purposes, and there 
    is nothing to indicate which of the two possibilities is more likely, then 
    the basic principle is that the sale is valid and permissible, because 
    Allaah says (interpretation of the meaning): “Allaah has
    permitted trading” [al-Baqarah 
    2:275]. 

    Then if the buyer uses it for anything haraam, the sin of 
    that is on him.

    The owners of these websites should keep an eye on what is 
    being placed on them and stipulate that no files which are forbidden 
    according to sharee’ah are placed on them. 

    Our advice is that people should not work in this field, 
    namely selling subscriptions, because even if he does not fall into haraam 
    for certain, by selling them to people who will use them for evil and 
    immoral purposes, he will be still uncertain as to whether his work is free 
    from sin. The Prophet (blessings and peace of Allaah be upon him) said: 
    “Leave that which makes you doubt for that which does not make you doubt.” 
    Narrated by al-Tirmidhi (2518) and al-Nasaa’i (5711); classed as saheeh by 
    al-Albaani in Saheeh al-Tirmidhi.  

    And he (blessings and peace of Allaah be upon him) said: 
    “Whoever guards against the doubtful matters will protect his religious 
    commitment from shortcomings and will protect his honour from slander, but 
    whoever falls into that which is doubtful will fall into that which is 
    haraam, like a shepherd who grazes his flock around prohibited land; he will 
    soon graze in it.” Narrated by al-Bukhaari (52) and Muslim (1599). 

    And Allaah knows best.
