Returning the purchased car under the option of choice upon the discovery of a defect

Question:
The brother Sa'd Ahmad says: I bought a car from a person, and he said to you, "You have the option for one day if a defect is found in it." When I arrived in my town, 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:
Yes, if there was a condition between you that you would return the car to him if a defect was found in it, then he is obligated to accept it, acting in accordance with the condition, based on the saying of the Messenger (peace and blessings be upon him) Also, even if there was no condition, if a defect is found in the item, you may return it and take the price, or keep it and take the value of the decrease to remove the harm from you. If he refuses to do that, then you proceed with it to the court. And. A ruling is issued and the case is examined.
