A summary of the concepts held by the Ahl al-Sunnah. The fundamental constants of the religion, situated between those who lean toward extremism and those who are negligent. Extremists misapply these fundamental constants, or some of them, placing them in contexts where they do not belong. This does not negate or invalidate these constants themselves. Rather, the obligation is to place them in their correct contexts. And to clarify their legal rulings according to the Shari'ah. They are called "constants" precisely because they are established and known as essential parts of the religion. Examples include loyalty and disavowal (al-wala' wa al-bara'), the implementation of the law of Allah, and striving in the path of Allah. Also, the rulings regarding disbelief and faith, which people are often driven away from by the blanket application of the term "takfir" (labeling others as disbelievers). When takfir is used without regard for the fulfillment of its conditions and the absence of its impediments, it is, without a doubt, a form of extremism and radicalism that must be rejected. However, when the rulings of takfir are governed by the proper legal constraints, and the conditions are met while the impediments are absent, it is not considered extremism. Rather, it is among the rulings of the religion that scholars have discussed extensively. This is evident in the chapters on the rulings of apostasy and apostates found in authoritative books of fiqh. A summary of the concepts held by the Ahl al-Sunnah.
