An Analytical Study of Implication and Independence from the Perspective of Aḥādīth and Late and Contemporary Islamic Scholars

The essential rules of religion are one of the most fundamental issues in the Islamic legal system. Adherence to it causes a person to benefit from the rights of citizenship in Islam; and opposing it will cause him to be deprived of the mentioned rights with titles such as apostate, kāfir and muḥārib. The essential rulings of religion refer to that part of religious knowledge whose reference to Sharia is not a place of doubt, and its criterion is the improvisation of the ruling and the subject that every Muslim knows at the beginning; and its acceptance does not need proof, because it is a rational axiom, and its meaning is so obvious that even non-Muslims are aware of it, such as prayer, fasting, Hajj, monotheism, prophethood and resurrection. However, there are some sayings about the implementation of the ruling and its effect, based on the hadiths and opinions of Islamic thinkers, some believe that denying the necessary rulings of the religion is an independent cause of disbelief. A group says that denying the essential rules of religion is a cause of disbelief if it is the cause of denying the mission.
