Investing in the shares of petroleum, gas

Q 1: Is it permissible to participate in companies and organizations whose shares are offered for public subscription, at a time when we have doubts about them and we wonder whether these companies or organizations are dealing in Riba (usury/interest), but we are not certain of this? It must be noted that we cannot become certain of this, as we have only heard it from other people.

(Part No. 14; Page No. 311)  A: It is permissible to participate in companies and organizations that do not deal in Riba or other Islamically prohibited transactions. However, if they do deal in Riba or any of the prohibited transactions, it is Haram (prohibited) to participate in them. If a Muslim has doubts about a company, it is better not to participate in it, acting upon the Hadith that states, “Leave that which makes you doubt for that which does not make you doubt.” The Prophet (peace be upon him) also said in another Hadith, “Anyone who avoids doubtful matters has protected their religion and their honor.” May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
