A legal rule is binding: Binding means that a legal rule must be respected and implemented by all those subject to it. It may impose multiple obligations, and those concerned must implement them if the legal rule is mandatory.Obligation is what distinguishes a legal rule from moral and religious rules, and the binding characteristic is evident in the penalty imposed on those who violate it. The relationship between legal rules and religious rules: Religion refers to the set of rulings, commands, and prohibitions established by divine laws and revealed to prophets and messengers for people to follow.Therefore, a mandatory legal rule is binding, and the obligation here is embodied in the penalty prescribed by law for those who refrain from implementing or violate that rule.However, if the legal rule is supplementary, individuals may agree to the opposite of what it stipulates.The intended meaning of the penalty is punishment or compulsion to comply and respect through the use of public force.The purpose of religious rules is that, in addition to regulating the behavior of individuals within society, religion also regulates a person's relationship with God and with himself.Religious legal rules differ in terms of purpose and penalty.It also holds people accountable for their pure intentions.
