Is trading in stocks, buying and selling, considered gambling due to the rise and fall of stock prices without a known commodity?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Is trading in banks through stocks, buying and selling, considered gambling due to the rise and fall of stocks without a known commodity? We ask you to address this matter, as it has become widespread in these days?

Answer:
Yes, people have now turned to buying and selling stocks. I have stopped doing so because of the ignorance, gharar (excessive uncertainty in a contract), and the lack of possession and receipt involved. It is all just talk; one sits and buys and sells, making a profit or a loss, without having received or taken possession of anything. It is merely talk. There is no commodity, and there is ignorance and gharar. It is not far-fetched to say that it is gambling. It is not far-fetched. Yes, gambling is every instance of gharar and every severe risk; this is gambling. Yes, every sale of an unknown item is gambling. Yes.
