Ibn Qayyim Al-Jawziyya
Ibn Taymiyyah left a considerable body of work, ranging from 350 according to his student Ibn Qayyim Al-Jawziyya to 500 according to his student al-Dhahabi. Oliver Leaman says that Ibn Taymiyyah produced some 700 works in the field of Islamic sciences. His scholarly output has been described as immense with a wide scope and its contents "bear the marks of brilliant insights hastily jotted down". It is the case however, that his works are not yet fully understood but efforts are being made, at least in the western languages to gain an adequate understanding of his writings. In his early life, his work was mostly based on theology and the use of reason in interpretation of scriptural evidences, with later works focusing on; refutation of Greek logic, questioning the prevalent practices of the time, and anti-Christian and anti-Shi'i polemics. Ibn Taymiyyah's total works have not all survived and his extant works of thirty five volumes, are incomplete. Extant books and essays written by ibn Taymiyyah include:
