<![CDATA[Buy Now Pay Later (BNPL) is a digital financing service that allows consumers to acquire goods or services upfront and complete payment later, either as a lump sum or through installments. The growth of BNPL raises legal questions regarding contract validity, consumer protection, riba (usury), gharar (uncertainty), and transactional justice. This study uses a normative legal method with statutory and conceptual approaches. Legal materials were analyzed based on statutory provisions specifically Law Number 8 of 1999 on Consumer Protection and Financial Services Authority Regulation (POJK) Number 32 of 2025 on the Operation of Buy Now Pay Later (BNPL) National Sharia Board-Indonesian Council of Ulema (DSN-MUI) fatwas, and scholarly literature published between 2021 and 2025. This study examines the legal position of BNPL under Indonesian positive law, the mechanisms of BNPL in light of the prohibitions against riba and gharar in Islamic economic law, and the application of justice principles in BNPL transactions. The results indicate that BNPL holds a recognized legal standing as a financing service regulated within Indonesia's financial system. However, formal legality does not automatically equate to Sharia compliance. The presence of riba and gharar depends on contract design (akad), fee structures, late penalties, information disclosure, and underlying financing mechanisms. Therefore, BNPL operations must prioritize contract clarity, transparency, consumer protection, and transactional justice.]]>
