Islam, for the firstime, gave the principle of establishing peace in society. People in the tribal age fought continually because war always leads to chain war, as the loser never accepts defeat and seeks revenge. The Quran says that reconciliation is the best. Reconciliation brings peace. Peace opens the door to opportunities by availing of which we can achieve any purpose. For this reason, peace must be established at a unilateral level.
