He then put them in motion in their orbits and ordained their (pace of) movement in the stages of their paths in order to distinguish with their help between night and day, and in order that the reckoning of years and calculations may be known by their fixed movements.

He put them in motion on their appointed routine and made them into fixed stars, moving stars, descending stars, ascending stars, ominous stars and lucky stars.
