2:191
وَٱقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُم مِّنْ حَيْثُ أَخْرَجُوكُمْ ۚ وَٱلْفِتْنَةُ أَشَدُّ مِنَ ٱلْقَتْلِ ۚ وَلَا تُقَـٰتِلُوهُمْ عِندَ ٱلْمَسْجِدِ ٱلْحَرَامِ حَتَّىٰ يُقَـٰتِلُوكُمْ فِيهِ ۖ فَإِن قَـٰتَلُوكُمْ فَٱقْتُلُوهُمْ ۗ كَذَٰلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ١٩١
And kill them [in battle] wherever you overtake them and expel them from wherever they have expelled you, and fitnah1 is worse than killing. And do not fight them at al-Masjid al-Ḥarām until they fight you there. But if they fight you, then kill them. Such is the recompense of the disbelievers.
