Christianity had become the state religion of the Roman Empire. By fifth century every trace of opposition from any other school of thought had completely vanished. In seventh century when the darkness of the dark age of the West was on its increase, the Quran, in the first decade of that dark century, produced the prophecy about atomic bomb in a country which had to its credit nothing but ages of darkness as long as the memory of historian could take his thought back into its history. A prophecy which was to remain dormant for more than thirteen centuries awaiting its fulfillment. A prophecy at which no human intelligence could venture with utmost surety even a day before the first December 1942, the day before Fermi, the Italian scientist achieved the first successful Fission Chain Reaction in Chicago.
