The Ruling on Buying Shares on Installment and Selling Them

Question:
Is it permissible to buy shares from Al-Rajhi Bank on installment and then sell them? To customers other than the bank? Is it permissible to buy shares from Al-Rajhi Bank?

Answer:
A good Shaykh, my brothers, the issue of shares is one I do not like to get into because the description is unknown. I do not know what is in them or what the operations are that are conducted in them; most of it is riba (usury or interest) and most of it is gambling.
The issue of shares involves ignorance and hidden matters about which we know nothing, so I do not see that I see dealing in shares. I do not recommend dealing in shares except in sound shares, such as shares in land, where you buy land and seek partnership in it and enter as a partner, or for example a manufacturing plant, such as for fertilizer. There is no harm in you partnering in the plant, unless it is extensive. The problem now is that factories and companies may have a sound foundation, but they deal in riba, they approach [transactions] with riba, and they place their money in investment. The matter is very difficult, to the point that even if its foundation is sound now, its income is haram, because they invest with riba, which is a great calamity. So the Muslim should avoid these things.
