Ijtihad

Ijtihad (ˌɪdʒtəˈhɑːd ; اجتهاد ijtihād, ʔidʒ.tihaːd; lit. physical or mental effort) is an Islamic legal term referring to independent reasoning by an expert in Islamic law, or the thorough exertion of a jurist's mental faculty in finding a solution to a legal question. It is contrasted with taqlid (imitation, conformity to legal precedent). According to classical Sunni theory, ijtihad requires expertise in the Arabic language, theology, revealed texts, and principles of jurisprudence (usul al-fiqh), and is not employed where authentic and authoritative texts (Qur'an and Hadith) are considered unambiguous with regard to the question, or where there is an existing scholarly consensus (ijma). Ijtihad is considered to be a religious duty for those qualified to perform it. An Islamic scholar who is qualified to perform ijtihad is called as a "mujtahid". Throughout the first five Islamic centuries, the practice of ijtihad continued both theoretically and practically amongst Sunni Muslims. The controversy surrounding ijtihad and the existence of mujtahids started, in its primitive form, around the beginning of the sixth/twelfth century. By the 14th century, development of Islamic Fiqh (jurisprudence) prompted leading Sunni jurists to state that the main legal questions had been addressed and the scope of ijtihad was gradually restricted. In the modern era, this gave rise to a perception amongst Orientalist scholars and sections of the Muslim public that the so-called "gate of ijtihad" was closed at the start of the classical era. While recent scholarship established that the practice of Ijtihad had never ceased in Islamic history, the extent and mechanisms of legal change in the post-formative period remain a subject of debate. Differences amongst the Fuqaha (jurists) prevented Sunni Muslims from reaching any consensus (Ijma) on the issues of continuity of Ijtihad and existence of Mujtahids. Thus, Ijtihad remained a key aspect of Islamic jurisprudence throughout the centuries.
