IBN HAZM [Abu Mahommed `Ali ibn Ahmad ibn Hazm] (994-1064), Moslem theologian, was born in a suburb of Cordova. He studied history, law and theology, and became a vizier as his father had been before him, but was deposed for heresy, and spent the rest of his life quietly in the country. In legal matters he belonged first to the Shafi`ite school, but came to adopt the views of the Zahirites, who admitted only the external sense of the Koran and tradition, disallowing the use of analogy ( Qiyas) and Taglid (appeal to the authority of an imam), and objecting altogether to the use of individual opinion (Ra`y). Every sentence of the Koran was to be interpreted in a general and universal sense; the special application to the circumstances of the time it was written was denied. Every word of the Koran was to be taken in a literal sense, but that sense was to be learned from other uses in the Koran itself, not from the meaning in other literature of the time. The special feature of Ibn Ilazm's teaching was that he extended the application of these principles from the study of law to that of dogmatic theology. He thus found himself in opposition at one time to the Mo`tazilites, at another to the Ash`arites. He did not, however, succeed in forming a school. His chief work is the Kitab ul-Milal wanNihal, or "Book of Sects" (published in Cairo, 1899).
