The Shari'ah Limits of Profit in Sales

Question:
He says: Honorable Shaykh, may Allah grant you success, is it permissible for a person who buys a commodity for ten riyals to sell it for fifty? And what are the Shari'ah limits for profit?

Answer:
This depends on the market; the market is what determines it. Goods may become scarce and prices rise, or goods may become abundant and prices fall, according to supply and demand. This is in the hands of Allah (Glorified and Exalted is He), and there is no fixed limit for profit because it follows the market. The Prophet (peace and blessings be upon him) said, when they asked him to fix prices, Price-fixing is not permissible except in cases of manipulation. Manipulation is prohibited. The one who artificially inflates the prices of goods without a real basis is prohibited from doing so, and he is compelled to sell at the same price as people sell at, according to what the goods are worth in the market. As for the one who does not manipulate, and the high price is only due to the scarcity of goods and the large number of buyers, no one can prevent that. This is in the hands of Allah (Glorified and Exalted is He); He is the One who lowers and raises, who constricts and expands, who constricts and expands, (Glorified and Exalted is He). Yes.
