He arranges matters from the heaven to the earth, and then it ascends to Him in a day which is equivalent to one thousand of the years which you count.

[32:5] Since the first audience of this verse was using the lunar calendar, we can find the velocity of the divine ruling in terms of km/day by calculating the sidereal distance covered by the moon in one thousand years. Interestingly, we end up with the speed of light, which is 299792.5 km/s. In other words, the light is 1000 x 12 x 27.321661 faster than the moon. Time is relative. See 22:47; 70:4.
