In surah Anbiya Allah says:" It is He who created night and day, the sun and the moon, revolving on its orbit. (33)"Why does Allah mention night first and day second, and after that sun first and moon second. Why isnt moon mentioned before the sun, because night was mentioned before the day?
There are many instances in the Qur'an in which Allaah has actually mentioned the night and the day, the sun and moon - all in this order. The reason that the night was mentioned before the day is that night signifies darkness and nothingness, and the mind associates darkness and nothingness with non-existence, so non-existence (darkness...the night) is mentioned first to allude to the logical order of creation (non-existence before existence, darkness before light, night before day). In addition, all that is associated with darkness is something that people wonder about and question more than all that is associated with light. For example, we would question and wonder about the reasons for blindness and deafness, where a person is in a state of no seeing and no hearing, more than we would wonder about why people see and hear. So Allaah has also placed first the night because people would wonder about it ("Why is there night?") more than the daylight.
And Allaah knows best.
