Cvitical Study about Consumable and Generative Govel to Le Law Ful

This article deals about gavel in Islam and it's typology in perspective of Islamic scholars of Shi'a and Sunni, Specially, division of gavel loan to consumable and generative. After readout the ideas about generative gavel and explaining the idea of some shi'a contemporary scholars that, like sunni's scholars, says it is lawful, we evaluated the eight arguments they bring up for this idea. We proved that no different between two kind of gavel according to Fegh and both of them are not allowed, because the focus of forbidding of gavel loan is provision of supernumerary from lender and this condition is available in both. In addition, the criterion of gavel, in Revayaat, is leaving the trade and production from lender not borrower and this is available in both. So there is no any reason to allow generative gavel.
