The Limit of Profit in Sales and the Difference Between Gharar (Excessive Uncertainty) and Ignorance

Question:
Honorable Shaykh, may Allah preserve you, is there a specific limit for profit, such as double, double that, or less or more?

Answer:
Profit does not have a specific limit because it follows the market, its rise and fall, and the scarcity or abundance of goods. So, profit has no specific limit. However, if the profit is the result of deceiving the buyer, through deception or trickery, this is not permissible. That is, the buyer does not know the value of the goods, and he is deceived by being charged an amount that is not present in the market and in which people do not usually engage in mutual deception. If he is cheated with excessive cheating, this is not permissible. Likewise, if the buyer is among those in dire necessity, needing to buy, and his necessity is exploited by adding an exorbitant increase, this is also disliked. This is disliked. A hadith has come regarding the prohibition of selling to one in dire necessity, meaning exploiting his necessity and lowering the value for him more than usual. This is not permissible because it involves harming those in need. Therefore, the profit should be moderate, and the value of the goods in the markets should be taken into account. Yes.
