What is the ruling on exaggerating the price of goods, and does the buyer have the option of inspection if he realizes he has been defrauded?

Sale is based on mutual consent between the contracting parties. If it fulfills the conditions and pillars, it becomes binding on both parties, and it is not permissible to annul it except through annulment by mutual consent (iqalah), which is recommended. The buyer is not allowed to compel the seller to take back the commodity, even if he finds it at a lower price in the market, because the seller has the right to profit as he wishes, without deception or fraud. There is no specific limit to profit, and it is permissible to buy a commodity at the market price by mutual consent.
