Al Anfal, 38 Ayah
8:38
قُل لِّلَّذِينَ كَفَرُوٓاْ إِن يَنتَهُواْ يُغۡفَرۡ لَهُم مَّا قَدۡ سَلَفَ وَإِن يَعُودُواْ فَقَدۡ مَضَتۡ سُنَّتُ ٱلۡأَوَّلِينَ ٣٨
Qul Lilladhīna Kafarū 'In Yantahū Yughfar Lahum Mā Qad Salafa Wa 'In Ya`ūdū Faqad Mađat Sunnatu Al-'Awwalīna
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.
