The present thesis is a critical examination of the two well-known post-Schachtian scholars of Hadith; James Robson and John Burton. Both scholars are major contributors to modern Hadith studies in the West. It assesses their main arguments and their methodological approaches to Hadith literature. It also provides a historical survey of the key arguments and works of their predecessors since the rise of the modern Western debates over the reliability of Hadith materials. This critical study points to the conclusion that Robson and Burton were heavily influenced by the sceptical attitude of Ignaz Goldziher and Joseph Schacht towards the historicity of Hadith. However, Robson is inclined to accept some aspects of the Muslim traditional view regarding the genesis of Hadith and its isnad system (chain of transmitters). Burton, on the other hand, expresses a sceptical stance towards the historicity of Hadith and argues that the development of Hadith originated from the exegesis of the Qur’an, having no historical basis in the teachings of Prophet Muhammad.
