Q: Is it halal to invest in Stock market like buying permissible shares like Petrol, gas, pharmaceuticals, cement etc. Since we are not the owner of the company how can we know how the owner has started that business? He may have brought some loan from the bank to start his business and later he may be introduced shares. In this case, how can we buy even halal shares and also, even if we are investing our halal amount to that share, there are million other investor who also invest their earnings (both haram and halal) in the same stock like mine. In this case, my amount is mingled with their amount and my profit is not halal. Correct me if I am wrong. Considering all this, can we say Stock as a whole is haram since we are not sure about all the investors.
A: It is not a shar`ee requirement to find out how the wealth was acquired unless you have serious doubts that the wealth was totally incorrect, like stolen wealth.
And Allah Ta’ala (الله تعالى) knows best.
