Is it permissible to follow the fatwa of one who issues a fatwa permitting stocks?

Question:
May Allah reward you, Your Eminence, father. The questioner says: There are those who issue fatwas on matters of stocks, and they are people we do not know, and we do not know where they acquired their knowledge, and they suddenly appeared before us. People rush to their fatwas and opinions on joint-stock companies, and some of them have elevated them to the rank of the great scholars. So what is my duty toward those who follow their fatwas?

Answer:
My brothers, as I mentioned to you, this has specialized authorities. As long as the specialized authority has not issued anything regarding it, a person should refrain. And if one says he is among the great scholars, or he is among the great scholars, meaning in terms of position, that does not guarantee that he will not err. He may err even if he is among the great scholars. If he errs on his own, but if he is with a group and they have discussed this matter, that is further from error. As for him acting alone and saying, "I am among the great scholars," even if he is among the great scholars, he errs. He should not praise himself, or people assume that he does not err because he is among the great scholars. That is a wrong assumption. Yes.
