You have a good example in Abraham and his companions: they said to their people: “We totally dissociate ourselves from you, and from the deities that you worship instead of Allah. We renounce you and there has come to be enmity and hatred between us and you until you believe in Allah, the One True God.” (But you may not emulate) Abraham's saying to his father: “Certainly I will ask pardon for you, although I have no power over Allah to obtain anything on your behalf.” (And Abraham and his companions prayed): “Our Lord, in You have we put our trust, and to You have we turned, and to You is our ultimate return.
