Surah Al-Baqara, Verse 191
وَٱقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُم مِّنْ حَيْثُ أَخْرَجُوكُمْ ۚ وَٱلْفِتْنَةُ أَشَدُّ مِنَ ٱلْقَتْلِ ۚ وَلَا تُقَٰتِلُوهُمْ عِندَ ٱلْمَسْجِدِ ٱلْحَرَامِ حَتَّىٰ يُقَٰتِلُوكُمْ فِيهِ ۖ فَإِن قَٰتَلُوكُمْ فَٱقْتُلُوهُمْ ۗ كَذَٰلِكَ جَزَآءُ ٱلْكَٰفِرِينَ
Translation — Sahih International
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.
