Is It A Virtuous Deed To Convert A Kafir To Islam?
Kafir means the one who denies a truth after realizing it is the truth. Kafir can be both in Muslims and Non-Muslims, when they deny a truth. If they did not deny the truth, they may be Muslims and non-Muslims but not Kafir. Yes, forsaking the attitude of denial to come to the truth of Islam is greatly rewarded by God.
