No it does not. It means his mercy "power up" his anger. So thats why I got confused. But anyways.

When it comes to the end of the world.. The mayans calender ended.. Why it became a "thing" that the world would end i dont know. If you go to Yuacatan, and are lucky enough to visit chitzen itza and tulum, you would understand what im talking about. As my guide told me "We have no clue how they managed to build it, absolutely no clue. We would not be able to do it today". I dont know what you mean with "true or justifiable", but if you have only found it in Islam, then maybe you have to expand your search ;).

Im gonna end the conversation on this post now, thanks alot for your comments, gave me some interesting perspective! I hope I see you in the comment section on my next post on chapter 4 in a couple of days :)
