Batas Dua Laut dalam Al-Qur’an: Studi Tafsir ‘Ilmi dan Ilmu Oseanografi

Abstract

This research examines the phenomenon of the boundary of the two seas as described in the Al-Qur'an, especially in Surah Ar-Rahman verses 19-20 and Surah Al-Furqan verse 53, through a scientific interpretation and oceanography approach. The background to this study is the uniqueness of this natural phenomenon, where two bodies of water with different characteristics do not mix, showing a sign of the greatness of Allah and the scientific relevance of the Qur'an. The aim of this research is to understand this phenomenon in depth through a combination of interpretive analysis and oceanographic data. The research was conducted qualitatively using the literature study method, using Al-Qur'an literature, classical and modern tafsir, as well as contemporary oceanographic studies. The research results show that this phenomenon occurs due to differences in physical properties such as salinity, temperature, and density that create a natural barrier layer or "barzakh." A clear example is found in the Strait of Gibraltar, where the Mediterranean Sea and Atlantic Ocean meet but do not mix. This finding not only strengthens the scientific miracles of the Koran, but also confirms the harmonious relationship between religion and science. The results of this research show that the phenomenon of the boundary between the two seas provides lessons about the balance of nature and its relevance in social life, namely the importance of tolerance and diversity in society.
