Gharar (Arabic: غرر) literally means uncertainty, hazard, chance or risk.[1] It is a negative element in mu'amalat fiqh (transactional Islamic jurisprudence), like riba (usury) and maysir (gambling).[2] One Islamic dictionary (A Concise Dictionary of Islamic Terms) describes it as "the sale of what is not present" — such as fish not yet caught, crops not yet harvested.[3][4] Similarly, author Muhammad Ayub says that "in the legal terminology of jurists", gharar is "the sale of a thing which is not present at hand, or the sale of a thing whose aqibah (consequence) is not known, or a sale involving hazard in which one does not know whether it will come to be or not".[5]
