Based on Quran and Sunnah, the author states that the principle of contract in muamalah activity is freedom. The majority of fiqh scholars agree that countenance (willingness) is the establishment of an agreement (contract). On the other hand, the prohibitions of usury, gharar, maisir / qimar are also not recommended in an engagement contract. These bans are intended to keep the property from being lost and eliminate hostility that occur in people due to this type of purchase. Finally, the contract conformity with Sharia maqashid is directed towards the realization of a variety of purposes for the welfare of mankind.indWith permission of the license/copyright holderIslamic LawValidityThe Contract SettingEconomic ethicsBusiness ethicsEthics of economic systemsMethods of ethicsPhilosophical ethicsJournal volume
