Mercy is power Think about it, can a person express mercy if he's weak? I guess not that wouldn't be mercy, I guess you can call that fear. so the stronger you get, the more merciful you become because there is no need to be such a bully where you can get what you want anytime you choose and in the form you will.(Then what is the need of mercy on you can just knock out your opponent? Well, that's the point you can knock him out any time).But wouldn't it seem cruel to take advantage of your opponent's weakness? Wouldn't it sound as if you are waiting for the opportunity to insult your opponent, rather than just achieve your goal? Besides, mercy acts as a key to people's hearts.They realize that no matter how bad their previous life was, they get a second opportunity to fix it. Why is mercy so important if I don't  get anything from it, besides winning people's hearts towards a certain cause. Although I could get it done on my own or maybe I don't need to get it done and I progress perfectly without it.To put it in another way, if my strength is eternal, is being merciful beneficial to me or to the object?  Well, what if the One we're pointing out here has everything perfected? I'd be sure that the idea of mercy would only be beneficial to the object not the Sustainer of mercy. This article was a trial to point out that as much as you know of Allah's mercy there is behind that perfected power, a reminder to fear Allah; a reminder to avoid what displeases Allah in order to avoid the wrath of Allah and in order to have a chance to enjoy the mercy of Allah. The mercy of Allah indicates that humans aren't thrown in there for the first time; they aren't thrown in the fire unless if they deny intentionally "the message that Allah is the only god worthy of worship and that the people believe in the last messenger of Allah to them". This gives a good idea why the forms of torture and pain in fire were so horrible. It's because those people got the opportunity to stand up on their feet and were shown signs of righteousness and yet they show no gratitude towards the sustained and they chose to be fluent tyrants in various forms.
