Sura 8 Al-Anfal (The Spoils of War), ayat 38

1. قُلْ لِلَّذِينَ كَفَرُوا إِنْ يَنْتَهُوا يُغْفَرْ لَهُمْ مَا قَدْ سَلَفَ وَإِنْ يَعُودُوا فَقَدْ مَضَتْ سُنَّتُ الْأَوَّلِينَ

   Say to those who have disbelieved (that) if they cease, what has previously occurred will be forgiven for them. But if they return (to hostility) - then the precedent of the former (rebellious) peoples has already taken place.

   8:38
