Say to the Unbelievers, if (now) they desist (from Unbelief), their past would be forgiven them; but if they persist, the punishment of those before them is already (a matter of warning for them). (38)
Tafsir
It is the principle of Islam that the individual is rewarded according to his deeds. However, by His grace the Almighty God has made special exemptions to this general principle: when a man is truly repentant, he will not be punished thereafter for his earlier deeds. Suppose a man spent his life in ungodliness, then he received the light of guidance, became a true believer and adopted the righteous life, in this case, he will be forgiven for the evil deeds done by him earlier; he will not be seized on the basis of his earlier sins.
