The basic doctrine of the Khawarij was that: “A person or a group who committed a grave error or sin and did not sincerely repent ceased to be Muslim”. According to them mere profession of the faith "there is no god but God; Muhammad is the prophet of God” did not make a person a Muslim unless this faith was accompanied by righteous deeds. In other words, good works were an integral part of faith and not extraneous to it. The second principle that flowed from their aggressive idealism was militancy, or Jihad, which the Khawarij considered to be among the cardinal principles, or pillars, of Islam. Contrary to the orthodox view, they interpreted the Qur’anic command about "enjoining good and forbidding evil"(Qur’an;3:104) to mean the vindication of truth through the sword.
The placing of these two principles together made the Khawarij highly inflammable fanatics, intolerant of almost any established political authority. They incessantly resorted to rebellion and as a result were virtually wiped out during the first two centuries of Islam.
Although till recently Chasidism has been considered essentially a story of the past, which left permanent influence on Islam, because of reaction against it. It forced the religious leadership of the community to formulate a bulwark against religious intolerance and fanaticism.
Takfiri Taliban Pakistan adhere to the doctrine, hence re emergence of Khawarji Fitnah in the shape of Takfiri Taliban Pakistan.
