To this date, technology has seen massive development and, it influences the economic field. The emergence of the metaverse has become an inevitable part of this progress. It serves as a digital world, wherein everyone is able carry out a vast array of activities, including economic transactions. The emergence of digital assets, that has encouraged serious discussion, is inseparable from Islamic law. One of these digital assets is the Non-Fungible Token (NFT). This digital asset is the focus of this study, specifically on for its posibility to become material guarantees. This article employs a qualitative study and presented descriptively through the perspective of Islamic law. The result of this study is that the pledged-object (marhūn) has certain primary conditions for it to be functional, namely: it is a property, it has value, it can be traded, its asset value is clearly known, and it is actually owned by the guarantor (rāhin). The concept of marhūn as a valuable object ultimately answers that NFT is included in the marhūn category. However, since NFTs do not stand alone if the transaction currency used in the metaverse is cryptocurrencies, al-rahn transactions using NFTs become less favourable considering Cyrptocurrency is deemed to be haram.
