Maintaining the red lines of religion: doctrinal, moral, legal jurisprudence, the purpose of preserving the religion is to guarantee and enforce the red lines of the definitive values of Islam in the three areas of Islamic beliefs, ethics and rules based on monotheism. These definite values, in religious terms, are the necessities of religion, which in no way can be reconsidered in the two areas of Islam and Imami Shi'ism. Otherwise, legally, the ruling will be to remove the scholar and the intentional appellant from the circle of Islam (Shiism and Sunnah) or Imami Shiism. And such a person will not be qualified to hold jobs and positions conditional on Islam or Shiism.
