This study aims to analyze the form of contract (akad), the transaction system, and the perspective of Islamic Economic Law on the practice of buying and selling mangoes in Tino Village, Tarowang District, Jeneponto Regency. This research employed a qualitative method with a case study design and a descriptive approach. Data were collected through interviews, observations, and documentation involving farmers, buyers, collectors, and religious leaders as research informants. The data were analyzed using data reduction, data presentation, and conclusion drawing techniques, while data validity was ensured through credibility, transferability, dependability, and confirmability tests. The findings reveal that the buying and selling of mangoes in Tino Village applies the ijon (advance purchase) contract, in which the transaction is conducted while the mangoes are still on the tree and have not yet matured. Payment is made in advance based on an estimated harvest, while the delivery of the fruit takes place at harvest time. The transaction process includes tree inspection, price negotiation, verbal agreement (akad), cash payment, and harvesting by the buyer. From the perspective of Islamic Economic Law, the practice fulfills the basic elements of a sale contract, namely the existence of the seller, buyer, and agreement. However, it does not fully comply with the principles of transparency, justice, and khiyar (the right of option), since the object of the contract remains uncertain in terms of quantity and quality, and all potential risks are transferred to the buyer. Consequently, the transaction contains elements of gharar (uncertainty), making it inconsistent with the principles of Islamic Economic Law. Therefore, this study recommends implementing more appropriate Sharia-compliant contracts, such as the salam contract or other transaction mechanisms that provide greater certainty regarding the object of sale, thereby ensuring fairness, transparency, and mutual benefit for all parties.
