At-Táuba 9:5 فاذا انسلخ الاشهر الحرم فاقتلوا المشركين حيث وجدتموهم وخذوهم واحصروهم واقعدوا لهم كل مرصد فان تابوا واقاموا الصلاة واتوا الزكاة فخلوا سبيلهم ان الله غفور رحيم ٥

Then, 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.

But when the forbidden months are past, then fight and slay the Pagans wherever ye find them, an seize them, beleaguer them, and lie in wait for them in every stratagem (of war); but if they repent, and establish regular prayers and practise regular charity, then open the way for them: for Allah is Oft-forgiving, Most Merciful.
