وَٱقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُم مِّنْ حَيْثُ أَخْرَجُوكُمْ ۚ وَٱلْفِتْنَةُ أَشَدُّ مِنَ ٱلْقَتْلِ ۚ وَلَا تُقَـٰتِلُوهُمْ عِندَ ٱلْمَسْجِدِ ٱلْحَرَامِ حَتَّىٰ يُقَـٰتِلُوكُمْ فِيهِ ۖ فَإِن قَـٰتَلُوكُمْ فَٱقْتُلُوهُمْ ۗ كَذَٰلِكَ جَزَآءُ ٱلْكَـٰفِرِينَ

And kill them wherever you overtake them and expel them from wherever they have expelled you, and fitnah is worse than killing. And do not fight them at al-Masjid al- Haram until they fight you there. But if they fight you, then kill them. Such is the recompense of the disbelievers.

— Al-Baqarah 2:191
