Is it permissible to join an e-marketing company that shares profits with its members in a guaranteed manner, without the need to bring in new members?

For it to be permissible for a participant to pay money to a company for investment, it is stipulated that the field of investment must be permissible, that the company not guarantee the invested capital except in cases of transgression or negligence, and that there be no guaranteed profit. Rather, they must agree on sharing the actual profit. If no profit is made, then there is nothing for the investor or the company. If a loss occurs without transgression or negligence, it is deducted from the capital. The Qirad (Mudarabah) contract becomes void if one or both partners stipulate a specific sum of money for themselves.
