The goal of true jihad is to attain a harmony between Islam (submission), iman(faith), and ihsan (righteous living). Under the sway of strong impulse, the man who is devoid of self control wilfully commits deeds that he knows to be fraught with future misery.
My sympathies and condolences go out to all those who have suffered, been injured, and those who have lost their loved ones in this terrible act of hatred and destruction. It is important that we do not allow divisive forces to weaken us ( as global peaceful world). We need to overcome these forces as one strong unified world, a truly global village.
