It is generally accepted by Muslim Jurists that the operation of conventional insurance does not conform to the rules and requirements of Shari'a. Takaful firms (that is, those insurance firms that choose to apply Shari'a to govern their operations and products) provide products and services corresponding to those offered by a conventional insurer to an insured (policyholder) but in a legitimate co-operative manner consistent with Islamic principles. Accordingly, takaful contracts are designed so as to be free of any gharar (uncertainty that would render them non-compliant with Shari'a), riba (interest) and other prohibitions.
