" In contemporary parlance, the term Salafi has come to acquire many different connotations. It has been used to refer to some groups who consider it obligatory to take up arms against all those - non-Muslims and Muslims - who are deemed to challenge or contravene the dictates of the Islamic foundational texts, the Qur'an and the normative example of the Prophet Muhammad (the sunna). At the other end of spectrum, it refers to a politically quietist trend, typified by the Saudi religious establishment, that rejects all beliefs and practices seen as compromising the oneness of God (tawhid) while leaving politics largely to the rulling elite. But the term Salafi is also used for, and by, those who reject the authority of the medieval schools of law and insist on an unmediated access to the foundational texts as the source of all norms. "
