Dealing with a company that sells gold by means of pyramid marketing
Question

                A company sells gold in a way that if you buy gold for $800 from it, you will be a member in this company. If you bring six buyers and they buy from the company, you will be an affective member and you will have continuous profits from this company forever according to how much it makes. Is it permissible to join this company?.
Praise be to Allah.
    It is not permissible to join companies that are based on 
    pyramid marketing, because this transaction involves gambling and consuming 
    people’s wealth unlawfully, and tricking and deceiving them by telling them 
    that they will make unbelievable profits, which are very rarely achieved by 
    those who join these companies. This has been discussed in detail in the 
    answer to question no. 40263,
    42579 and
    45898. 

    Moreover, the company sells gold, and the gold does not reach 
    the purchaser until several days after the contract is done, and this is 
    another reservation about this company. When selling gold for cash, it is 
    stipulated that the gold and the money be handed over in the same sitting as 
    that in which the contract is drawn up, because the Prophet SAWS (peace and 
    blessings of Allaah be upon him) said: “Gold for gold, silver for silver, 
    wheat for wheat, barley for barley, dates for dates, salt for salt, like for 
    like, same for same, hand to hand. If any of these types are different, then 
    sell however you like, so long as it is hand to hand.”  Narrated by Muslim 
    (2970) from the hadeeth of ‘Ubaadah ibn al-Saamit (may Allaah be pleased 
    with him).  

    Riyals, dollars and other kinds of currency come under the 
    same rulings as gold and silver, so it is not permissible to buy gold for 
    any kind of currency unless it is hand to hand. 

    If the subscriber is going to pay the price of the gold up 
    front, then the gold is going to be sent to him by mail, or via a shipping 
    company, then this means that it is not hand to hand, so this transaction is 
    haraam. 

    Some of these companies offer the option of paying by 
    instalments, which is another reason why it is haraam, because it is not 
    permissible to sell gold by instalments, rather it must be sold hand to hand 
    as stated above. 

    Conclusion: It is not permissible to join companies that are 
    based on pyramid selling, because their dealings are based on gambling and 
    consuming people’s wealth unlawfully, and because they involve riba when 
    selling gold by instalments or when delaying handing over gold until after 
    the sitting in which the contract is done. 

    And Allaah knows best.
