Is it permissible to earn profit through referral and promotion for the "Arab Web Business" website at a rate of $1 for each publisher and $5 for each advertiser who registers through the marketer, knowing that the profit system is not hierarchical and is limited to members who register directly through him?

It is permissible to work with the website and earn from it if what it publishes is permissible, provided that what is advertised is permissible, and that the subscriber does not pay fees for subscription. If these conditions are met and regulated, there is no objection to promoting it. The commission for bringing in customers does not affect permissibility as long as it is known, because this falls under the category of permissible brokerage. However, it is a condition that what is published and advertised must be permissible and not a promotion for something forbidden; otherwise, the earning would be forbidden, and the one pursuing it would be assisting in sin and transgression.
