Allah did not create that save in truth.(Thus)does He explain the Signs in detail, for a people who know. " Commentary : There are words used in the Qur'an for the sun, such as/ siraj/ and/ d iya'/, which signify a strong and intensive light. As for the moon, the words used are/ nour/ and/ munir/ which signify even dim light as well.

From among the tokens of Allah's designs in the world of existence and His absolute command over the universe, one can name the wise order spread throughout the entire cosmos. Do you not behold what a heat and what a light He has given to the sun They change with the changes of the sun in the morning and during the day, and manifest themselves in the variety of the seasons of the year. It varies at dawn and midday, not exceeding the limits at any extreme.

If the sun's heat exceeds what it already is, all the earth would be incinerated, and if it decreases from its present temperature, the earth and what ever is in it will freeze, and in both cases, life will terminate in its totality. If the light of the sun was extinguished you would no longer be able to see the moon for it borrows its light from the sun.

It spreads its light at nighttime over the earth, residing temporarily in its different stages: as the full moon, as a crescent and occasionally disappearing altogether. Through observing the regularity of these changes mankind can keep track of their days, months and years, organize their work and make plans with a schedule. That is, it is an accurate natural calendar that can benefit both the sage and the illiterate for keeping track of the rhythm of their work in their daily- lives.

This privilege of the moon is besides the light that it gives us. The verse says: "He it is Who made the sun a radiation and the moon a light, and determined it by stations, that you might know the number of years and the reckoning(of time).
