The Quran's description of the formation of the day and night aligns with modern scientific understandings of the sun's formation. While the Bible suggests that light existed before the creation of the sun, the Quran avoids this contradiction. In Quran 17:12, it is stated that night preceded the day, which is consistent with the idea that the sun’s fusion process began later in the early stages of the solar system's formation. According to scientific knowledge, the sun was formed from a molecular cloud, and it took time for it to accumulate enough pressure and heat to start nuclear fusion, thus producing light. This period of darkness before the sun began to shine is described in the Quran, aligning with the current understanding of solar system formation.

This perspective is consistent with the scientific concept of the sun gradually igniting through fusion after a phase of accumulation, prior to which there was no sunlight. Whilst these verses might not necessarily reference the scientific findings mentioned here, they showcase how, even the most hard to imagine realities explained by the Quran, can be shown to be permissible with modern scientific discoveries.
