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

When the Sacred Months have passed, slay the polytheists wherever you find them. Capture them, besiege them, and ambush them at every possible location. However, if they repent, establish prayer, and give in charity, let them go their way. God is Forgiving and Merciful.
