Is it permissible to work for a company that owns interest-bearing shares?

If the company deals with usury, it is not permissible to work for it, due to the words of the Prophet, peace and blessings be upon him: "Allah has cursed the one who consumes Riba, the one who gives it, the one who records it, and the two witnesses to it," and due to His Almighty's saying: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression). However, if the company does not deal with usury and its operations are permissible, but its owner has usurious shares separate from his company, then working for it is permissible.
