The document discusses how the Quran revealed 1400 years ago that the sun will eventually expire. It describes the process by which the sun will die as its core runs out of hydrogen fuel and begins fusing helium, then carbon. When these fuels are exhausted, the sun will expand into a red giant and engulf nearby planets, then shrink into a dim white dwarf star. Modern astrophysics has confirmed this process, showing the Quran possessed sublime knowledge of the sun's future death.
