Defective item delivered to purchaser

In principle, a sale is concluded with a proposal from one party and acceptance from the other party. However, if the buyer finds a defect in the item on taking possession or on taking delivery, then he or she will be entitled to return the item for a full refund.

Products purchased from non-Muslim companies may be returned without any difficulty if they are found to be defective, and the purchaser will receive a refund in full. We as Muslims should learn the laws of trade and commerce and practice upon these laws as prescribed in the Shariah. In conclusion, the seller should refund the item (in your instance) if it was found defective.
