Yea, Imran Khan is really becoming a politician :-) But he is right.
We know that the Qur'an ordains justice for all, even with the enemy.
5:2 ...... Let not the hatred of a people lead you to transgression, because they prevented you from going to the Sacred Masjid (48:25). Help one another in acts of collective benefit and righteousness, and do not help one another in deeds that hurt humanity and in creating a wedge between people. Be mindful of God. His Law of Requital is strong in grasping.
5:8 O You who have chosen to be graced with belief! Be upholders of justice for the sake of God as witnesses to the truth. Let not the hatred of any people move you away from justice. Deal justly. That is closer to being upright. Be mindful of your duty to God. God is fully Aware of what you do.
5:9 God promises the protection of forgiveness and a great reward to those who attain belief and do works that fulfill the needs of people and increase the well being of society.
