Is it permissible for the buyer to withhold the remaining amount from the seller who claimed that some of the furniture does not belong to him, and refused to compensate the buyer for the shortage and damage after a prior agreement to sell everything in the house as is?

If a person buys furniture after seeing it, then finds a defect or a shortage upon delivery, and the furniture does not change quickly, then the sale is valid because knowledge of the sold item was obtained through the prior viewing. If the buyer finds the sold item in the same condition without change or shortage, then the sale is binding upon him. However, if there is a defect or shortage, the buyer has the option between upholding the sale or annulling it. If he chooses to uphold it, he has the right to claim from the seller the value of the defective or missing part from the total price.
