Qur'an 4:91

سَتَجِدُونَ ءَاخَرِينَ يُرِيدُونَ أَن يَأْمَنُوكُمْ وَيَأْمَنُوا۟ قَوْمَهُمْ كُلَّ مَا رُدُّوٓا۟ إِلَى ٱلْفِتْنَةِ أُرْكِسُوا۟ فِيهَا ۚ فَإِن لَّمْ يَعْتَزِلُوكُمْ وَيُلْقُوٓا۟ إِلَيْكُمُ ٱلسَّلَمَ وَيَكُفُّوٓا۟ أَيْدِيَهُمْ فَخُذُوهُمْ وَٱقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ ۚ وَأُو۟لَـٰٓئِكُمْ جَعَلْنَا لَكُمْ عَلَيْهِمْ سُلْطَـٰنًا مُّبِينًا

Ye will find others who desire that they should have security from you, and security from their own folk. So often as they are returned to hostility they are plunged therein. If they keep not aloof from you nor offer you peace nor hold their hands, then take them and kill them wherever ye find them. Against such We have given you clear warrant.
