Is money earned from watching foreign movie and cartoon advertisements, which remains as an unswept balance after stopping this action due to its impermissibility, halal or haram?

It is not permissible to earn money through subscriptions to profit-making websites that require a fee, due to the element of gambling and the potential for usury involved. The contract is void and must be rescinded, and the paid amount returned. The inquirer may withdraw the amount to complete the subscription fee they paid. As for what they earned before knowing of its impermissibility, there is no sin in benefiting from it, for Allah Almighty says: "So whoever receives an admonition from his Lord and desists, he may have what is past, and his affair rests with Allah."
