Surah Al-Baqarah, Verse 191

وَٱقۡتُلُوهُمۡ حَيۡثُ ثَقِفۡتُمُوهُمۡ وَأَخۡرِجُوهُم مِّنۡ حَيۡثُ أَخۡرَجُوكُمۡۚ وَٱلۡفِتۡنَةُ أَشَدُّ مِنَ ٱلۡقَتۡلِۚ وَلَا تُقَٰتِلُوهُمۡ عِندَ ٱلۡمَسۡجِدِ ٱلۡحَرَامِ حَتَّىٰ يُقَٰتِلُوكُمۡ فِيهِۖ فَإِن قَٰتَلُوكُمۡ فَٱقۡتُلُوهُمۡۗ كَذَٰلِكَ جَزَآءُ ٱلۡكَٰفِرِينَ١٩١

wa-uq'tulūhum ḥaythu thaqif'tumūhum wa-akhrijūhum min ḥaythu akhrajūkum wal-fit'natu ashaddu mina l-qatli walā tuqātilūhum ʿinda l-masjidi l-ḥarāmi ḥattā yuqātilūkum fīhi fa-in qātalūkum fa-uq'tulūhum kadhālika jazāu l-kāfirīna

And kill them [in battle] 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-Ḥarām until they fight you there. But if they fight you, then kill them. Such is the recompense of the disbelievers.
