A company sells various types of products to customers. Some customers return products, and in other cases, the shipping company returns undelivered shipments. The company then aggregates these diverse items—such as toys, kitchenware, electrical appliances, etc.—into large boxes and resells them to contractors and intermediaries. We purchase them from these intermediaries and sell them in shops by displaying them on tables at prices lower than the original retail price. The customer has the right to open the product packaging and test it before purchasing.
There are two methods of purchase:
1. Blind Purchase: The goods are sold without a manifest (list of contents), and the load is sold at a fixed price for all shipments.
2. Manifest-Based Purchase: The goods are sold with a manifest provided by the seller. However, due to administrative and accounting procedures between the company and the intermediary, this manifest is sent two weeks after the purchase. The variety is similar to the first type, but the specific items are known. The price varies from one load to another. In this case, the goods are often displayed and sold before the manifest is received due to the administrative delay. What is the ruling of Islamic Law (Shariah) on this?
