Ayah 2;

وَالْقَمَرِ إِذَا تَلَاهَا

and i swear by the moon as it follows it (the sun).

Talaa = to follow. (tilaawa = to read, since the reader follows the lines on the page.)

talaaHa = follows Her (the sun).

The moon is given the subservient position to the sun, as it (talaa) follows the sun.

Ash Shawkani:– When the moon becomes complete – it follows the sun. i.e. It is reflecting its light off the sun.
[between 9mins – 11mins]

al Farraa’ said: – talaaha – takes from it. The moon takes from the light of the sun. It is in a subservient position.

So this was a view of the salaf too. With the moon being in the subservient position to the sun, and borrowing its light too.
