There are many people who talk about the men of God, some talk about the places that show signs of God, some people say that every single thing that exists on earth is God, and all such people fell into the trap of many wrong representative of God.
To understand the miracles of Allah and Islam, one must understand that creator has revealed an instruction manual in which all the problems of man are discussed; every single problem of thoughts, actions and behaviors is discussed. Signs of God are simply termed as miracles.
Miracles of Allah and Islam can be witnessed when one study the last revelation of God, in which more than thousand verses speak about science. Science has advanced itself in recent sixty to hundred years and Quran was revealed more than 1400 years ago, all the verses of Quran are now being confirmed by the science.
