فَإِذَا انسَلَخَ الأَشهُرُ الحُرُمُ فَاقتُلُوا المُشرِكينَ حَيثُ وَجَدتُموهُم وَخُذوهُم وَاحصُروهُم وَاقعُدوا لَهُم كُلَّ مَرصَدٍ ۚ فَإِن تابوا وَأَقامُوا الصَّلاةَ وَآتَوُا الزَّكاةَ فَخَلّوا سَبيلَهُم ۚ إِنَّ اللَّهَ غَفورٌ رَحيمٌ

And when the sacred months have passed, then kill the polytheists wherever you find them and capture them and besiege them and sit in wait for them at every place of ambush. But if they should repent, establish prayer, and give zakah, let them [go] on their way. Indeed, Allah is Forgiving and Merciful.
