Surah Ya Sin (Ya Sin) 36 : 38

Explanatory Note

The sun also runs its set course:

that is laid down by the will of the Almighty, the All-Knowing. And for the moon We have determined phases until it finally becomes like an old date stalk. Neither the sun can overtake the moon, nor can the night outrun the day. Each floats in its own orbit. (Verses 37-40)

When the night comes, light disappears and darkness spreads: this is something everyone sees every day in every corner of the world, except for polar areas. Despite its daily occurrence, it is a remarkable sign that deserves contemplation. The Qur’ānic description here is unique as it shows the day intertwined with the night and then God strips the day off the night to let darkness spread. We may perhaps further appreciate the unique way the Qur’ān uses to express this image when we remember how it actually happens. As the earth rotates facing the sun, every spot of it actually comes face to face with the sun when the day spreads over it. When the rotation of the earth changes and that spot no longer faces the sun, the day is stripped off it so as to plunge it into darkness. The same thing happens over every little part of the earth in progression, as if the light of day is pulled away or stripped to allow darkness to replace it. Thus the wording here accurately describes the reality.

“The sun also runs its set course.” (Verse 38)

It was generally believed that the sun stays in its position but turns around its axis, but it has recently been confirmed that it moves in a single direction in the great universal space, and astronomers have calculated the speed of its movement as being 12 miles per second. God Almighty, who knows its movement and destination, says that it moves along its course to a particular destination which is known only to Him. He alone knows when and what this is.
