Over the past two decades, the growing number of works on Ibn Taymiyya (d. 728/1328) has confirmed the ever-growing interest of scholars in the famous Ḥanbalī theologian of Damascus, who is undeniably one of the most studied and well-known medieval Muslim theologians. In addition to the diversity of the subjects covered, the analysis of Ibn Taymiyya’s writings demonstrates the author’s vast erudition and his argumentation methodology, which was both efficient and complex. Even though he has been the subject of research in both the Arab world and Western scholarship, grey areas remain regarding what can be called Ibn Taymiyya’s source methodology. Based on a close reading of a sample of the Ḥanbalī theologian’s writings, this article attempts to provide some preliminary information on Ibn Taymiyya’s way of reading, selection and use of sources in his argumentation methodology. Far from being an exhaustive study that would require a complete analysis of the Ḥanbalī scholar’s work, this article aims to be a preliminary study to suggest analytical and research perspectives.
