This essence is usually abstract and beyond the reach of ordinary human experience. This phenomenon is the focus of this article, so that it becomes a discussion that can be accepted by humans in general.  This paper uses library research (library research) with data sources in the form of scientific articles, books, documents, journals and other sources of a library nature. The data was collected and then analyzed in depth using content analysis techniques and presented descriptively. The research results show that the phenomenon of the revelation of the Koran itself contains metaphysical elements such as the nature of God, His creation and humans so that metaphysics cannot be separated from the practical life of the Islamic religion. The beauty and value of a process in Islam in studying the Koran and  and position on earth, namely as servants and caliphs.

Of all the thoughts of Islamic philosophers, there are still many Muslims who are unable to properly translate their thoughts into people's lives, so that many Muslims lose direction in navigating this life, as a result they move away from Islamic teachings. The aim of this research is to analyze how the thoughts of this Islamic philosopher can be adopted by Muslims in order to carry out Islamic teachings in a sustainable manner. The research method applied is descriptive qualitative with documentation studies, where the data collection technique uses documentation studies. In accordance with the results of existing research, it can be concluded that there are several concepts from Islamic thought that Islamic philosophers have adopted in order to teach Islamic teachings on an ongoing basis, namely the ideas of monotheism, epistemology, metaphysics, ethics, political philosophy, Sufism, Islamic law and theology.

This research explores the use of iterative methods in conjunction with the Finite Difference Method (FDM) for solving partial differential equations (PDE). The central challenge addressed is the computational inefficiency and slow convergence that often arise when utilizing traditional numerical methods, particularly in large-scale systems. The study aims to develop a more efficient iterative approach to solve PDEs by minimizing computational time while ensuring the stability of the obtained solutions. The primary methods proposed include iterative solvers such as Gauss-Seidel and Successive Over-Relaxation (SOR), which are applied to numerical solutions derived from FDM. The research demonstrates that iterative methods, especially SOR, achieve faster convergence with fewer iterations compared to conventional methods like the Finite Element Method (FEM), which tends to be slower and more resource-intensive for large-scale problems. The study highlights the advantages of iterative solvers in efficiently handling large, sparse linear systems and reducing computational costs. In addition, it shows that these methods are capable of providing stable solutions, thereby maintaining accuracy with significantly lower computational effort. The results suggest that iterative methods, when applied in combination with FDM, offer a practical and scalable solution for solving complex PDEs. These methods are especially beneficial in engineering and theoretical physics applications where large-scale simulations are prevalent. The study concludes with recommendations for future research, which should focus on further optimizing solver parameters, exploring hybrid approaches, and extending the methods to more complex PDEs with non-linearities or irregular geometries. By doing so, these techniques could contribute to even more efficient and practical solutions for real-world applications.

The simplest gas and approaching the simplest properties of a true gas is an ideal gas. Ideal gases satisfy the ordinary gas equation, while real gases do not always satisfy the ideal gas equation. Gas laws such as Boyle's Law, Charles' Law, and Gay Lusaac's Law, show the relationships between macroscopic units of various processes and formulations.This research is a type of literature review research by looking for theoretical references that are relevant to the cases or problems found.The results of Boyle's experiments stated that if the temperature of a gas in a closed vessel is kept constant, the gas pressure will be inversely proportional to its volume. Gay-Lusaac's law states that the volume of gas in a closed vessel is maintained constant, the gas pressure will be proportional to its absolute temperature. Charles's law states that at constant pressure, the volume of an ideal gas of a certain mass is directly proportional to its temperature. An ideal gas is a concept in physics which assumes that a gas consists of very small particles with zero volume, do not interact with each other, and move randomly in a closed container. This concept also assumes that collisions between gas particles and the walls of the container are elastic, meaning that kinetic energy is maintained in each collision.

Islamic science and Western science are two rich scientific traditions with a long history and significant contributions to science. Despite some similarities, they also have fundamental differences in methodology, epistemology, and goals. Islamic science flourished during the Middle Ages, driven by intellectual curiosity and the urge to understand God's creation. Muslim scientists combined the revelations of the Koran with observations and experiments to produce advances in a variety of fields, including astronomy, mathematics, physics, optics, and medicine. They emphasized the importance of a systematic scientific method, using hypotheses, experiments, and observations to test theories.Western science, on the other hand, emerged in Europe during the Renaissance and Enlightenment. Western science is characterized by its emphasis on rationalism, empiricism, and secularism. Western scientists challenged the authority of religion and tradition, and focused on developing more rigorous scientific methods, such as controlled experiments and testable hypotheses.

The problem of evil remains one of the most persistent and challenging issues in Christian philosophy. This paper explores the philosophical dimensions of suffering through a Christian lens, focusing on the paradox of divine goodness in the presence of moral and natural evil. Drawing from classical theodicy and contemporary Catholic thought, the study examines how the mystery of the Cross offers a unique theological and philosophical response to suffering. Special attention is given to the thought of Augustine, Aquinas, and modern Catholic philosophers such as Henri de Lubac and Josef Pieper. The paper argues that Christian philosophy does not attempt to explain away suffering but rather provides a framework in which suffering can be redemptive, meaningful, and even transformative when united with the suffering of Christ. By grounding human suffering within the narrative of salvation history, Christian philosophy affirms that evil does not have the final word. The research also reflects on the existential implications of hope, patience, and grace in enduring suffering, making a case for a distinctly Christian metaphysical response to theodicy. This study contributes to ongoing discussions in Christian existentialism, ethics, and metaphysics by reaffirming the coherence of faith and reason in addressing one of the deepest human questions.
