A pyramid-marketing company that sells da’wah tapes
Question

                There is a company that operates like the “Business” company, but in return for money paid they sell da’wah tapes that guide to the truth. How should we respond to them?.
Praise be to Allah.
    In the answer to question no
    40263 we have 
    already stated that it is haraam to participate in pyramid-selling schemes 
    like the “Business” company, even if these companies sell a real product 
    that has some value, because the aim is not to sell that product, rather the 
    aim is marketing, and pyramid marketing is based on ambiguity and consuming 
    people’s wealth unlawfully. 

    Shaykh Saami ibn Ibraaheem al-Suwaylim said: 

    The essential idea behind pyramid marketing is simple and may 
    be summed up as follows: A person buys the company’s products in return for 
    the opportunity to convince others to do what he did (i.e., to buy the 
    company’s products too), in return for which he takes commission. Then each 
    of these people who joined the scheme convinces yet others to join too, and 
    the first one gets additional commission, and so on. 

    He also said concerning the “Tasweeq net” (marketing net) 
    company – which is a company that sells real products –  

    This system mentioned in the question is a pyramid marketing 
    scheme, no matter what form it takes, in which the person who joins it 
    convinces others to buy so that they can also join the marketing scheme. So 
    long as the commission is greater than the value of the product, the primary 
    goal behind buying is the commission and the product is secondary. Based on 
    that, this is not allowed according to sharee’ah because it involves 
    ambiguity and consuming people’s wealth unlawfully, since the one who joins 
    the scheme does not know whether he will succeed in convincing others to 
    join or not. If he succeeds then he will profit at their expense from their 
    subscriptions, otherwise he will lose the money that he paid to join the 
    scheme, and those who joined through him will be subject to the same risks. 
    Each level in the pyramid will lose, unless there is a level beneath them 
    which can bear the brunt of the loss, and so on.
