Is it obligatory to sell items that were bought with money from selling a “Conquer” game account, which is impermissible, and donate their price as charity, or has Allah forgiven what is past?

The game "Conquer" is prohibited due to its inclusion of impermissible elements according to Islamic law. Therefore, it is not permissible to sell it, and the money earned from it is illicit (khabith). Whoever earned it while ignorant of its prohibition and then repented, may benefit from it and is not required to dispose of what they purchased with it, based on the Almighty's saying: ﴿So whoever receives an admonition from his Lord and desists, he may have what is past.﴾ As for whoever earned it while knowing of its prohibition, they should donate it as charity.
