What is the ruling on dealing with NazcoSoft Company, which pays 100 Riyals for each golden membership registration worth 167 Riyals, which is a share in the company that receives its profits at the end of the year or through placing a paid advertisement, and 20% for each website sold, knowing that this business is neither a pyramid scheme nor a network marketing scheme?

The transaction described is either a brokerage or a pyramid scheme. If it is a brokerage, meaning you promote the company, and you receive a commission or fee from anyone who registers, advertises, or purchases through you, then there is no harm in it, provided the company's field of work is permissible. However, if it is impermissible, then it is not allowed. If it is a pyramid scheme, then it is unlawful due to the elements of gharar (uncertainty) and gambling it entails. The percentage you receive when any customer you bring purchases from one of their websites could be known if the price of the websites is fixed and known, in which case it is valid as a fee or commission for brokerage. However, if the price of the websites is unknown, then the percentage will be unknown, and according to the most preponderant opinion, the fee must be known.
