Poro

There is a book on this earth, which is not from the earth. Millions of books have been written on that book. Millions are being written right now. That book was the first audiobook on this earth. It claimed it is not the word of any human. It is from the Creator of the universe. It claims to distinguish the good from the bad. It claims to give light. It changed millions of individuals, changed nations.
Which book is that? Al Quran.

Poro is a book of reflections on the Quran. From scientific and logical point of view.
