Al Baqarah Ayah 191

وَٱقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُم مِّنْ حَيْثُ أَخْرَجُوكُمْ‌ۚ وَٱلْفِتْنَةُ أَشَدُّ مِنَ ٱلْقَتْلِ‌ۚ وَلَا تُقَـٰتِلُوهُمْ عِندَ ٱلْمَسْجِدِ ٱلْحَرَامِ حَتَّىٰ يُقَـٰتِلُوكُمْ فِيهِ‌ۖ فَإِن قَـٰتَلُوكُمْ فَٱقْتُلُوهُمْ‌ۗ كَذَٲلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ ١٩١ Kill them wherever you come upon them and drive them out of the places from which they have driven you out. For persecution is far worse than killing. And do not fight them at the Sacred Mosque unless they attack you there. If they do so, then fight them—that is the reward of the disbelievers.
