IHTIKAR احتكار
Hoarding up grain with the object of raising the price. Used for monopoly of all kinds. Abu Hanifah restricts its use to a monopoly of the necessaries of life. It is strictly forbidden by Muhammad, who is related to have said: “Whoever monopoliseth is a sinner”; “Those who bring grain to a city to sell at a cheap rate are blessed, and they who keep it back in order to sell at a high rate are cursed.” (Mishkat, book xii. ch. viii.)
