Scientology in Egypt has no official presence because non-monotheistic religions are not recognized in Egypt. The Church of Scientology has claimed that Egypt is one of the "countries in which Dianetics and Scientology services are ministered",[1]: 450 but there are no known membership statistics available. In 2002, two Scientologists were detained by Egyptian authorities under the charges of "contempt of religion". As of 2010, books authored by Scientology founder L. Ron Hubbard and printed by the Church of Scientology for its front groups were being distributed in Egypt—even bearing the approval of Al-Azhar, the highest Sunni learning institution in the Muslim world. Narconon, an organization which promotes Hubbard's drug abuse treatment, has a branch in Ismailia Governorate called "Narconon Egypt".
