Research On The Creation Of Night

This Booklet is a Research on the Creation of Night.
Scientists around the world have done several researches on the subject of "Light" but I have never seen any
document or book on the "Night". I have found information on the creation of Night from the Glorious Book "Quran"
Quran is not a scientific book but it's a book of signs. These signs are facts which are already discovered or to be discovered in the future.
