al-Iman al-Kabeer was written by ash-Shaykh al-Islaam Ibn Taymiyyah to explain some of the correct stances in the understanding of Imaan in comparison to the incorrect understanding that is commonly found among some of the most misguided groups such as the Mu'tazilah, Khawaarij and Jahmiyyah. Printed on in one huge volume that consist of 788 pages and printed on yellow paper by Dar al-'Asimaah (Riyaad). Very Important book in learning the correct creed.
