In the Holy Quran, the Almighty also makes mention of seven heavens or levels of skies. Presuming what has been mentioned up until now pertains to the first level, how are human reason and comprehension expected to bear the mysteries of the others?
Allah, glory unto Him, asserts:
“Who created the seven heavens one above another; you see no incongruity in the creation of the Beneficent Allah; then look again, can you see any disorder? Then turn back the eye again and again; your look shall come back to you confused while it is fatigued. And certainly We have adorned this lower heaven with lamps and We have made these missiles for the devils, and We have prepared for them the chastisement of burning.” (al-Mulk, 3-5)
Now, lift your head and turn your gaze to the skies! Reflect on the innumerable objects in space, faltering not even for a split second in their orbit amid this grand order, each loaded with an underlying mystery and wisdom in its movement.
If the Earth did not rotate on its axis, one side of it would constantly be bright, while the other side doomed to perpetual darkness. There would have been no way of separating the hours of work from the hours of rest.
There is also inherent wisdom in the fact that it takes 24 hours for Earth to rotate once around its axis. Were it to take longer, Earth would have been something like Mercury, where the difference between daily and nightly warmth exceeds 1000 C° (1,832 F). Excess heat would have scorched the Earth in those long days, leaving only for a menacing cold come the evening, freezing everything in its wake.
With these in mind, take note of how the Almighty has blanketed the day with night and rendered the former a time to work, while the latter a time to rest. Think of the manifestations of Divine Power and Mercy in their relentless pursuit of each other!
Again, had the Earth not rotated around the Sun with a tilt of 23 degrees and 27 minutes, there would not have been the four seasons so vital for life. Furthermore, had the Earth not been given this tilt, water evaporating from the oceans would have surged north and south, turning continents into daunting icebergs.
If the moon, say, was 50,000 miles further away from where it is now, the tides would have been so enormous that the continents would have been deluged twice on a daily basis. Even the mighty mountains would have eroded to utter annihilation, in almost the blink of an eye.
So therefore, do not be stuck in awe of the sky simply for the sake of its immensity and the myriad of stars it boasts. Instead, proceed to reflect on its Creator and how He has fashioned and ordered it all! How is it that the Almighty holds those massive stars together without a visible pillar or peg?
Just think of the Sun and the Moon; do they ever breakdown? Is there ever a time when they are sent to repair? While traveling in their predestined orbits do any of the countless objects in space step out of their Divine course and have accidents?
