The Religious Insurgency of the Khawarij
Compiled and Translated: 'Abbas Abu Yahya (Jeddah KSA)
Paperback: 53 pages
Ibn Taymiyyah (died 728H) stated: "The Khawarij were the first ones to decare a Muslim to be outside of the fold of Islam due to his sins - rather to be precise, with what the khawarij thought were sins! And they made lawful the spilling of the blood of Islam due to this."
