As a muslim i believe that there will be time that no one believe in God-Allah.
Prophet said that there will be time when no one know why a person was killed, and earthquakes will appear, a huge amout of people will die in east and west at once, alot of not legal sexual relations, alot of wars. Then the time that follow these things will be fulled with believers especially when Christ peace be upon him will come, after the death of Christ peace be upon him people will loose thier faith with time and will come time when believers die and remain only persons who dont believe in any thing, one of these persons will say "my old grandfather was saying Allah" and with time no one will remain and pronounce the word Allah or God, no one religion will remain, even Quran wont be presented. Killing and raping and drinking will be diffused and then the day of judgment will begin, which is another chapter in humans life.
