A type of riba (ربا) that arises in sale transactions (buyu’) involving barter exchange (muqayadhah) of commodities belonging to the same genus (genera) in unequal amounts and deferred delivery by either or both parties. An excess benefit usually goes to one of the parties to a sale or exchange of different ribawi items where one of the commodities is not delivered at the time of transaction, but later in the future. This type of riba is prohibited by shari’ah because one party benefits at the expense of the other (as reflected in the better quality or the difference between delivery dates for exchanged items).

Riba al-yad (ربا اليد) is also known as riba al-fadhl, riba khafi, riba al-sunnah, and riba al-buyu’.
