Do you not see [i.e., know] that Allāh causes the night to enter the day and causes the day to enter the night and has subjected the sun and the moon, each running [its course] for a specified term, and that Allāh, of whatever you do, is Aware?
Do you not see that Allah shortens the night to lengthen the day, and shortens the day to lengthen the night? He also set the orbits of the sun and the moon, so each moves in its orbit for a fixed length of time. Do you also not see that Allah is aware of everything you do; none of your actions are hidden from Him, and He will requite you for them.
