Yes, it is true that buying and selling without immediate exchange can be a subject of controversy.
There are several reasons that make this matter a point of contention:
Islamic law: Islam requires the immediate exchange for the validity of the sale, meaning the delivery of the goods and the monetary compensation in the contract session or soon thereafter. This condition aims to ensure that each party receives their due rights and to avoid disputes.
Civil law: Civil laws vary in different countries regarding the conditions for the validity of contracts. Some laws require immediate exchange, while others allow for a delay in the exchange.
