The ruling on investing in companies that deal in riba

There is a questioner who asks about a company called the Pharmaceutical Company. This company is established and operating, and it has shares, but it wants to expand its capital; so it has issued new shares for people to subscribe to.He says: He states that at the very beginning, the company distributed profits before it started operating. Before it began its work, it gave profits to people. This raises the suspicion that these profits were riba profits obtained by placing money in banks.So the questioner says: What is the ruling on subscribing to it now? And what is our duty toward this company?

The answer is, as I said: This is riba, as long as it distributed profits before it started operating. However, it is obligatory for him to give away what he received and donate it in charity to rid himself of it. There is no harm in the new subscription.
