The ruling on selling a car with a defect

Question:
This questioner says: I bought a large car from a person, and he said, “You have the option for two days if there is a defect in it.” When I arrived in my country, I found a major defect in the engine, so I went back to him, and he said, “I have nothing for you.” Is there any advice for people like these?

Answer:
This is a dispute that is referred to the judge. However, it is obligatory for the seller to advise the buyer. If he knows that there is a defect in the car or the commodity, he must not conceal it; he must disclose it and say, “There is such-and-such a defect in it.” If he did not know that there was a defect, but it later turns out that there is one, then the buyer has the option: either to return it and take the price, or to keep it and take the compensation for the defect, meaning the compensation for the loss that occurred due to the defect. Yes.
