Apostate prophet asks Arabic question; What is ajal musama?

In answer to the video "43 Scientific Mistakes in the Quran"

When the Quran refers to the cosmic bodies moving on to their appointed term/ajalin musamma 13:2,31:29,35:13,39:5 it is referring -as is clear from the contexts- to the Day of Resurrection where all the universe will be destroyed and created anew

"and He made the sun and the moon subservient (to you); each one pursues its course to an appointed time/ajalin musamma; He regulates the affair, making clear the signs that you may be certain of meeting your Lord".

Ajalin musamma refers to the appointed end of a thing 6:2,40:67. In 36:38 it speaks of the sun "running", which is a perfect description of the sun's movement accross the galaxy. The word denotes rapid movement contrary to the perceived motion of the sun. So it cannot be speaking of sunrise and sunset, which certainly arent rapid motions. The sun is "running" to its place of rest, its end point. And the end of its rapid course will be, as with allthings, the day of resurrection. The variant reading attributed to both ibn Abbas and ibn Masud in which they recited 36:38 LAmustaqarrin/no resting place, instead of LImustaqarrin/to its resting place is inauthentic.
