Is it permissible to deduct the price of the broken television from the debt that the merchant owes me?

Whoever buys a defective item that diminishes its value has the choice between returning it and taking back its price, or keeping it and taking compensation for the defect. This compensation is the proportion of the difference between the sound value and the defective value, and it is taken from the price. If the seller refuses to do so, then you may take the equivalent of your right by refraining from paying the debt that equals your right, or by finding a stratagem to avoid paying it.
