What is the ruling on dealing with the company (Biznas), which is based on pyramid marketing, where a person buys its products for $99, then markets them to others for specific commissions that increase with the growing number of participants in the pyramid?

"Biznas" transactions are forbidden because they are based on gambling (maysir) and unlawfully consuming people's wealth. They involve deception and exploiting greed, and the use of a product within them is merely a trick to achieve this. Furthermore, they do not resemble permissible brokerage (samsarah) due to their inclusion of conditions and methods that are religiously prohibited.
