What is the ruling on subscribing to and profiting from "traffic-surfing" companies that rely on ad exchange and money doubling, knowing that these websites do not contain advertisements that conflict with religion or explicit materials, and that profit is made by automatically opening other websites or by recruiting new subscribers, and is it a condition to pay a fee to upgrade membership in order to receive profits?

The question is unclear, and the answer can be summarized in three points:

1. Working on those websites: Its ruling depends on the products and offers advertised and the method of advertisement. If they are permissible according to Islamic law, then participation is lawful and the commission is permissible; otherwise, it is not. 2. Not being entitled to a commission until a minimum amount of work is achieved: There is no harm in this, as long as it is by agreement and does not contradict Islamic law. 3. Conditioning the receipt of commission on buying a share: This is a void condition and it is not permissible to stipulate it, because the worker's right to his wage is established upon performing the work, as the Prophet (peace be upon him) said: "Give the worker his wage before his sweat dries." However, if the worker is compelled to buy the share to obtain a permissible wage, there is no sin upon him, and the sin is upon the one who compelled him.
