This research departs by looking at the development of modern science in the current era which seems increasingly sophisticated and complex. With the technology as a result of human creation and creativity, it can facilitate work and problems in all areas of life, including in the field of science. Along with the sophistication and advancement of the world of science with the help of this technology, the Islamic world is also feeling its impact, especially in the field of natural verses interpretation (kauniyyah verses). Among the natural phenomena that scholars and scientists have long debated is the expanding universe theory, namely the theory that the universe is experiencing expanding, (not constant). Zaglul an-Najjār as one of the contemporary mufassir in the field of science said that since 1400 years ago, the Qur’ān in his kauniyyah verses explained nature and its contents, phenomena and evidence of modern scientific discoveries. This shows the miracles of the Qur’ān in the present era so that people understand the truth of the Qur’ān. In his commentary book “Tafsīr al-Āyāt al-Kauniyah fī al-Qur’ān al-Karīm” he discusses the topic of this expanding universe theory in particular in one of his studies namely sūrah aż-Żāriyāt verse 47. The results of the study stated that the Qur’ān not contradict with the latest modern scientific research which is the result of human effort. The word lamūsi'ūn in the fragment of verse 47 indicates the expansion is still happening, continuing until now. In line with the findings of scientists that universe expands from a very small point starting from the Big Bang.
By looking at this reality, it can be understood whether the fields of religion and science complement each other or do they contradict each other? Then how exactly is the relationship between religion and science, especially in Zaglul an-Najjār interpretation of this theory? In this regard, this research takes the perspective of Ian G. Barbour as a contemporary scientist who examines the issue of the relationship between religion and science. His typology that he compiled in the field of relations between religion and science is very well known and has been widely used by theologians, scientists and scholars as well as academics in connecting between them. So the focus of this study discusses two topical issues, namely the how the method that Zaglul an-Najjār used in interpreting the expanding universe theory based and how his interpretation if seen from Ian G. Barbour’s perspective. By using the descriptive analysis method it can be seen after conducting research, that interpretation source that he used is research by scientists and by looking at the development of modern science. His interpretation type is tafsīr bir-ra’yi, his interpretation method is tahlilī and maudū’i and use ‘ilmī style. Then it’s known that by looking through the perspective of Ian G. Barbour, his interpretation can be classified into integration typologies, especially natural theology and systematic synthesis.
