Most Libyans adhere to the Sunni branch of Islam, which provides both a spiritual guide for individuals and a keystone for government policy. Its tenets stress a unity of religion and state rather than a separation or distinction between the two, and even those Muslims who have ceased to believe fully in Islam retain Islamic habits and attitudes. The post-revolution National Transitional Council has explicitly endeavored to reaffirm Islamic values, enhance appreciation of Islamic culture, elevate the status of Qur'anic law and, to a considerable degree, emphasize Qur'anic practice in everyday Libyan life with legal implementation in accordance to Islamic jurisprudence known as sharia. Libya has a very small presence of Ahmadis and Shias consisting of Pakistani immigrants, though unrecognized by the state . History During the seventh century, Muslims, who were spreading their faith, reached Libya to spread the message. The urban centers soon became substantially Islamic, but widespread conversion of the nomads of the desert did not come until after large-scale invasions in the eleventh century by Bedouin tribes from Arabia and Egypt. A residue of pre-Islamic beliefs blended with the Islam of the Arabs. Hence, popular Islam became an overlay of Quranic ritual and principles upon the vestiges of earlier beliefs—prevalent throughout North Africa—in jinns (spirits), the evil eye, rites to ensure good fortune, and cult veneration of local saints. The educated of the cities and towns served as the primary bearers and guardians of the more austere brand of orthodox Islam. Islam in Gaddafi's Libya Under the revolutionary Gaddafi government, the role of orthodox Islam in Libyan life became progressively more important. Muammar al-Gaddafi was a highly devout Muslim, with an expressed desire to exalt Islam and to restore it to its proper—i.e., central—place in the life of the people. He believed that the purity of Islam had been sullied through time, particularly by the influence of Europeans, both during and after the colonial period, and that Islam's purity must be restored by such actions as: the restoration of sharia to its proper place as the basis of the Libyan legal system, the banning of "immodest" practices and dress, and the symbolic purification of mosques. Gaddafi also believed in the value of the Quran as a moral and political guide for the contemporary world, as is evident from his tract, The Green Book, published in the mid-1970s (see The Green Book, ch. 4). Gaddafi considered the
