Surah Al-Anfal, ayah 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 madat sunnatul-awwalīn

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.⁴⁴⁵
