BBA is a contract where goods are delivered immediately but payment is deferred to a future date. It involves the prompt delivery of goods to the buyer while postponing payment until a later specified date or through installments. Hadith provide evidence that deferred payment contracts were permitted by the Prophet Muhammad, including instances where he engaged in such contracts and where the payment terms included profit for the seller in addition to the price. For BBA contracts, there must be an offer (sighah), an asset or goods, and an agreed upon price between the buyer and seller. BBA is commonly used in Malaysia for medium to long-term financing of goods like property, vehicles, education costs, and other assets.
