The original post...it's very vague because 'following Allah' can mean a thousand different things. Evil and satanic can mean several things, as well.
Diwana, I think you've misunderstood the concept of inner peace. I see inner peace as being completely grateful for everything you have and for what you are. That doesn't mean you don't strive for more, it just means that you appreciate what you have.
Most of us, including myself, are constantly stressed, and tend to focus on negative thoughts far too much. Being stressed is actually counter productive, and all the negativity only breeds more negativity in our life. It becomes a vicious cycle which can only be broken if we change our thinking into something positive.
We can mke anytyhing we like of the meaning of peace but
1- The actual post did not ask for inner peace.
2- Inner peace as we see it has not produced a single beneficial thing for mankind so far.
All the inner peace champions sat on their butts and thought about the creator and lived life away from the world.
While those who had lack of satisfaction from available means and resources looked hard and found solutions to make thigs better in life.
Now same inner peace masters fly in a plane and get to England and USA in a matter of hours and give full page ad to attract others so they can teach inner peace to these inner peace seekers.
Sarcastic but I hope you got the message.
While inner peace is good but too much of it makes a person lazy and oblivious of the surrounding.
Peace.
