I think that LOVE is the word that can solve ALL our problems in this World.
How could you still persist on disobeying Allah instead of loving Him and trying to please Him?
It is as if Allah is the one looking for you and calling you to return to Him.
If, after us know all this about Allah’s Mercy, we still insist on not feeling ashamed of our sins?
I think the world would be heaven on earth, People would start to become more merciful and forgiving towards each other because When you love Allah , there's no room in your heart for loving yourself , therefore everyone becomes more giving.
So i see that if all people loved their lord Allah realy the world will change surely to better not just better.........to the Best.
