Immanent Anthropologists and Transcendent Natives,

Islam is based on the Quran, one of the holy books considered by Muslims to be revealed by God, and on the teachings (hadith) of the Islamic prophet Muhammad, a major political and religious figure of the 7th century CE. Islam is based on the unity of all religious philosophies and accepts all of the Abrahamic prophets of Judaism, Christianity and other Abrahamic religions before Muhammad. It is the most widely practiced religion of Southeast Asia, North Africa, Western Asia, and Central Asia, while Muslim-majority countries also exist in parts of South Asia, Sub-Saharan Africa, and Southeast Europe. There are also several Islamic republics, including Iran, Pakistan, Mauritania, and Afghanistan.

• Sunni Islam is the largest denomination within Islam and follows the Quran, the hadiths which record the sunnah, whilst placing emphasis on the sahabah.
