The word moon (Qamar), is used exactly 27 times in the Quran together with its derivatives. This number is equal to the number which is the moon’s ecliptic cycle around the world. (We mentioned the Quran’s description of the moon in the 15th and 16th chapters of our book’s first section). The Quran indicates that both the sun and the moon are based on calculation. (Gracious, 55) The sun’s and the moon’s definition in terms of mathematics is interesting and these words in question are mathematically coded in the Quran.
