Recent social media trends in Indonesia highlight increasing incidents of couriers being confronted by customers during Cash on Delivery (COD) transactions. These confrontations typically stem from buyers refusing to pay for goods upon delivery, citing discrepancies between the product received and their expectations. Islamic financial ethics, specifically *fiqh muamalah*, are being invoked to address the issue, with arguments that cancelling an order without legitimate reason is ethically problematic. Experts suggest buyers have a responsibility to inspect goods thoroughly *before* completing the COD process. The debate centers on balancing consumer rights with the fair treatment of delivery personnel and the potential financial burden placed on businesses. This issue reflects growing pains within Indonesia’s rapidly expanding e-commerce sector and the challenges of the COD payment method. The discussion aims to establish clearer guidelines for responsible online purchasing behavior.
