Ijtihad

An endeavor of a qualified jurist to derive or formulate a rule of law to determine the true ruling of the divine law in a matter on which the revelation is not explicit or certain, on the basis of evidence found in the Quran and the Sunnah. Express injunctions have no room for Ijtihad. Implied injunctions can be interpreted in different ways by way of inference from the accepted principles of the Sharia.
