These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Paranoia Fuel: It's stated that The End of the World as We Know It (and the Judgement Day that follows) will happen when you don't expect it (it can potentially happen the next Friday), for the knowledge of it is Allah's alone.
