What is the ruling on investing in advertising companies that offer 2% of the share value ($4) for 20 days, provided their ads are browsed daily to obtain this percentage, and the capital and percentage are recovered after the period ends? Is it necessary to know how these companies invest their money?

Dealing with these companies is forbidden for several reasons:

1. Fraud and impermissible deception, as the company requires merely visiting its websites to mislead users into believing that browsing has increased. 2. The amount paid is a usurious loan, because its repayment is guaranteed with a specific increase conditioned on visiting advertising websites. 3. If this work is considered an ijarah (definition) (leasing/hiring contract), it is a فاسدة ijarah (corrupt contract) because the wage is not specified. It is also an ijarah conditioned on a loan, which invalidates it. 4. The website contains impermissible elements from a Sharia (definition) perspective.
