Earth's Atmosphere as Protection

The Quran refers to the sky as a protected ceiling, which aligns with scientific understanding that Earth’s atmosphere protects life by blocking harmful solar radiation and reducing the temperature extremes between day and night.

وَجَعَلْنَا ٱلسَّمَآءَ سَقْفًۭا مَّحْفُوظًۭا ۖ وَهُمْ عَنْ ءَايَٰتِهَا مُعْرِضُونَ

And We made the sky a protected ceiling; yet they turn away from its wonders.
