Whatever is related here about Doomsday refers apparently to an unknown world. However, such evidence exists as points to its veracity. An example of this is the present world itself. The very existence of the world proves that another similar or different world may come into existence. Furthermore, certain extraordinary aspects of the Quran prove that it is the Book of God. (For details see The Quran: An Abiding Wonder and The Call of the Quran by the commentator).
