A great deal of work has been done by the researcher in this book, allowing him to publish for the first time several unpublished Risalah of Shaykh al-Islam ibn Taymiyyah as well as additional passages to some of the texts already available.
It is the result of a great and meticulous research work, which brings us unpublished Fatawas and Risalah of Ibn Taymiyyah.
The latter are gathered by theme, which makes this book even more valuable.
