Is it permissible to sell company shares on credit?

Question:
Is it permissible to sell company shares on credit?

Answer:
There is a distinction regarding company shares:
If the shares represent land, cars, or real estate, it is permissible to sell them on credit. However, if the shares represent money, they may not be sold except hand-to-hand. If they are money, and have not been invested in real estate, land, cars, or the like, they may not be sold on credit; they must be sold hand-to-hand because they are money. For example, if he has money, such as one thousand riyals, he may sell it for one thousand riyals only, or for another currency, such as dollars, hand-to-hand, or for pounds, or the like, Saudi or Egyptian pounds.
The point is that if it is currency, he sells it for the same amount he delivered, or he sells it for another currency, hand-to-hand, because it is still money and has not been invested in real estate. However, if it has been invested in real estate, cars, or food, it is permissible to sell it on credit without cash.
