From the earliest moments in human history, the relationship between God, the universe, and humanity has been a subject of discussion, not only among followers of divine religions but also among representatives of positive sciences. Various theories have been put forth, and numerous evaluations have been made regarding the details of this relationship. The discussions around this topic continue to be relevant today From the perspective of divine religions, one of the most notable and fundamental aspects of the Quran-centered revelation (...) system in Islam is the clear distinction between the Creator and the created. According to this understanding, all entities outside of Allah are categorized as created beings, and they owe their existence and continuity to Allah, who is incomparable to anything else. Additionally, the Quran frequently emphasizes that the universe was created with precise measures, balance, and order. Indeed, these criteria form the starting point of the teleological argument, which extensively utilizes them to demonstrate the existence of Allah, especially His unity. All of this suggests that nothing in the universe is the result of random chance; rather, it implies that the universe embodies a sense of regularity or lawfulness. In our view, “Sunnatullah” is a term used in the Quran to express this regularity or lawfulness. The issue of the unchangeability of the “Sunnatullah” has brought forth discussions on determinism first through causality and then, within the context of determinism, debates on deism. Indeed, interpreting the concept of “Sunnatullah” through a rigid deterministic understanding may open the door to deism, while attributing events in the universe to chance rather than standard laws brings about a process leading to atheism by excluding the Creator. Therefore, it is crucial to approach the phenomenon of “Sunnatullah” in the context of the relationship between God, the universe, and humans in a way that eliminates these risks. For this reason, we have chosen to focus on the relationship between “Sunnatullah” and legality within the context of “immutability.” In addressing this topic, we have attempted to consider not only the data of revelation but also the factual domain. In doing so, our fundamental approach has been not to view the Quran as a purely scientific book and not to operate under the assumption that “everything happening in nature is detailed in the Quran.” However, we have endeavored not to overlook the fact that there is harmony between nature/physics, created by the same entity, and the Quran. In our opinion, this harmony has the potential to create an objective foundation for reaching belief in Allah based on the movement from nature/physics. While composing our text, we emphasized concept analysis and highlighted historical and empirical realities. Document analysis was chosen as the method for this qualitative research. We explored the framework of the concept of “Sunnatullah” and attempted to elucidate its relationship with causality. In our research, the term “Sunnatullah” has been used in a sense encompassing all laws pertaining to society and nature within the context of the relationship between God, humans, and the universe. Additionally, it has been argued that the introduction of different laws into the nature and operation of anything in various areas and conditions of life does not imply that the law is susceptible to change. In our view, the unchangeability of the law refers to the detail that the same law will come into effect under the same conditions. Conditions may change, but the law that comes into effect according to those specific/appropriate conditions remains unchanged. Indeed, in line with His infinite knowledge and power, Allah has not overlooked any detail and has established a law for every possible situation in the universe with its causes and effects. The relationship between “Sunnatullah” and causality occurs in this context. (shrink)
