At Tawbah Ayah 5

فَإِذَا ٱنسَلَخَ ٱلْأَشْهُرُ ٱلْحُرُمُ فَٱقْتُلُواْ ٱلْمُشْرِكِينَ حَيْثُ وَجَدتُّمُوهُمْ وَخُذُوهُمْ وَٱحْصُرُوهُمْ وَٱقْعُدُواْ لَهُمْ كُلَّ مَرْصَدٍ‌ۚ فَإِن تَابُواْ وَأَقَامُواْ ٱلصَّلَوٲةَ وَءَاتَوُاْ ٱلزَّكَوٲةَ فَخَلُّواْ سَبِيلَهُمْ‌ۚ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ ٥ But once the Sacred Months have passed, kill the polytheists ?who violated their treaties? wherever you find them, capture them, besiege them, and lie in wait for them on every way. But if they repent, perform prayers, and pay alms-tax, then set them free. Indeed, Allah is All-Forgiving, Most Merciful.
