Al-Furqan bayna Awliya al-Rahman wa Awliya al-Shaytan - Ibn Taymiyyah

Book of Shaykh al-Islam ibn Taymiyah defining and explaining the differences between the Allies of Allah azza wa jall and the Allies of Shaytan.

In the image as those of whom Allah speaks here {Verily the friends of Allah are (those) on whom fear (cometh) not, nor do they grieve?  Those who believe and keep their duty (to Allah).} [Yunus] and here {Shall I inform you upon whom the devils descend? They descend on every sinful, false one. They listen eagerly, but most of them are liars.} [Ash-Shu'ara].
