And thus, with no knowledge of either the foundations of Islaam or its branches, he brought in his books calamities, upon calamities. The bid'ahs of the Jahmiyyah, Mu'tazilah, Ash'ariyyah, Mufawwidah, Jabariyyah, Ittihaadiyyah, he brought the maxims and philosophies of secular atheist Jews (Communism) and fused them with Islam, claiming Islam is a fusion, blend of such philosophies along with Christianity, he attacked the Companions of Allaah's Messenger on account of the "social justice" he envisaged through those Communist Marxist ideals. Then in 1952 he was instrumental in the July revolution, a Socialist, Marxist, Leninist type revolution through which Jamal Abdul-Nasser came to power, and when he fell out with this former comrade and was put into prison in 1954, he then started penning down the Communist Revolutionary Manifesto in his books "Milestones" and "az-Zilal", which became the madhhab of the Khawaarij. And he did not outline his revolutionary doctrines because he was imprisoned, being forced due to the circumstances, out of anger and resentment, as some people claim, rather he was already ideologically upon that, and he'd plotted one successful socialist revolution already. So the Communist Revolutionary Manifesto and what it contained of the notions of "social justice" [think Dhul-Khuwaisarah and the distribution of "capital"] and "revolution" [think the revolution of Abdullah bin Saba'] became the aqidah of the 20th Century Khawaarij, nurtured upon the works of Sayyid Qutb, who strangely, enough came out in the name of "al-Haakimiyyah".
