Abstract
In M.Nesprava’s article "Theoretical Foundations of Radical Salafism", the presence of a conceptual core in the radical Salafism doctrine is shown and the main formation stages of this core are analyzed. Also, the role of the ideas by such authors as Ahmad ibn Hanbal, Muhammad ibn ʿAbd al- Wahhab, Syed Abul A'la Maududi and Sayyid Qutb in the formation of the conceptual core is argued. The characteristic aspects of the interpretation by radical Salafists of such concepts as tawhid, takfir and jihad are demonstrated.
