Allah in the Arabic language means "the Deity". Notice that there are seven components that make up the word Allah (alif, hamzat wasl, lam, lam, shadda, dagger alif, and ha). This can correlate with the Seven Heavens in Sura 2:29, which can be considered to be symbolic for the Seven chakras of the body. 

Now notice how the word Allah makes up the numbers 13, 13, and 6/9.

If it were 13 and 9, it would correspond with the 13 heavens and 9 underworlds in Aztec Cosmology. The reason why I'm going with that is because of that correlation.
