Is it permissible to sell shares of a company listed on the stock exchange to individuals or companies, knowing that its earnings are from ill-gotten gains?

It is not permissible to trade stocks on the stock exchange if there are Sharia violations, whether selling them to someone who knows they are forbidden or not, because that is cooperating in sin and transgression.

However, if the intention is to sell shares to a person whose wealth is unlawful, and if the stock transaction is permissible according to Sharia conditions: 1. If the price of the shares is from the very substance of unlawful wealth that has not been mixed with lawful wealth: the transaction is forbidden. 2. If the price of the shares is from wealth in which lawful and unlawful have mixed: the preponderant opinion is that this transaction is disliked due to the presence of doubt.
