This practice is also carried out at UD Agus Jaya, a building materials store located in Mojomalang Village, Parengan District, Tuban Regency. Buyers who purchase building materials in large quantities usually make a down payment first and are allowed to take the materials gradually throughout the construction process, while the final payment is made at the end of construction without a clearly defined payment deadline. This uncertainty poses a potential risk of loss to the seller. Therefore, this issue is important to study in order to assess the validity of the sale and purchase contract and examine the potential presence of gharar (uncertainty) in the transaction. This study uses a field research method with a normative-empirical approach and a descriptive-analytical nature to examine the practice of deferred payment sales at UD Agus Jaya. The theoretical framework includes the concepts of contracts (akad), sale and purchase (jual beli), and gharar to analyze the potential uncertainty within the transaction. Data were collected through observation, interviews, documentation, and literature study to obtain valid and comprehensive information. The results of the study indicate that the sale and purchase contract for building materials using a deferred payment system at UD Agus Jaya, in terms of its pillars (rukun), fulfills the requirements for validity according to Islamic law. However, there are issues regarding the contractual conditions due to the absence of a clearly defined payment period, which has the potential to render the contract fasid (defective) according to the majority of scholars. This practice also contains elements of gharar yasir (minor uncertainty), which is still tolerated as long as it does not cause significant harm. Therefore, improvements are needed in administrative management, the determination of a clear payment schedule, and transaction documentation to avoid potential gharar and disputes, and to ensure that the rights and obligations of each party are protected in accordance with Islamic law, and in line with the principles of justice, transparency, and legal certainty in Islamic jurisprudence.
