The Church of Scientology has no official presence in Egypt and there are no known membership statistics available. In 2002, two members were detained by Egyptian authorities under the charges of "contempt of religion". However, some books by the founder, L. Ron Hubbard, have started to appear in several Egyptian bookstores in the late 2000s, and were even approved by Al-Azhar, the highest Sunni learning institution in the Muslim world.
