And why is the adjective ‘Munir’ used for the moon?

And why is the adjective ‘Munir’ used for the moon? It is probably because the word ‘Siraj’ means light and the lamp from which light comes out and this is consistent with the nature of the sun that according to scientific researches the light of the sun belongs to itself.

“And He it is Who has made the night and the day to succeed each other for him who desires to reflect or desires to be thankful.” This noble verse still continues to introduce the Lord of the universe and states another part of the system of the existence. It says: “And He it is Who has made the night and the day to succeed each other for him who desires to reflect or desires to be thankful.” It is the regular system that rules the day and the night which alternatively substitute each other.

This system is in work for millions of year. It is the system that if does not exist the life of man will be destroyed by intensity of heat and light or darkness, and this is an attractive reason for those who want to know Allah. We know that the system of day and night is generated from the movement of the earth around itself.

Its gradual and regular changes, that is continually the duration of one of them increases and the other one decreases, is because of its axle slope in regard to its orbit, which, during a year, causes the four seasons. If the earth rotated faster or slower than its usual speed, in one case the nights would get so longer that all things would be frozen, and in other case the days would be so long that the sun would burn everything.

Moreover, the centrifugal force could be so intense that the earthly creatures would be thrown out into the space. In brief, on one hand, the study of this system awakes the theology nature in man. (Perhaps the application of the phrase ‘desires to reflect’ refers to this fact), and on the other hand, it awakes the thanking spirit in man and the phrase ‘desires to be thankful’ may refer to this matter.
