Quran 9, Al-Tawba (Repentance) ⓘ

9:5Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful.

فَإِذَا انْسَلَخَ الْأَشْهُرُ الْحُرُمُ فَاقْتُلُوا الْمُشْرِكِينَ حَيْثُ وَجَدْتُمُوهُمْ وَخُذُوهُمْ وَاحْصُرُوهُمْ وَاقْعُدُوا لَهُمْ كُلَّ مَرْصَدٍ فَإِنْ تَابُوا وَأَقَامُوا الصَّلَاةَ وَآتَوُا الزَّكَاةَ فَخَلُّوا سَبِيلَهُمْ إِنَّ اللَّهَ غَفُورٌ رَحِيمٌ
