Sura al-Baqara 2:191

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

wa-aqtulūhum ḥaythu thaqiftumūhum wa-akhrijūhum min ḥaythu akhrajūkum wa-l-fitnatu ashaddu mina l-qatli wa-lā tuqātilūhum ʿinda l-masjidi l-ḥarāmi ḥattā yuqātilūkum fīhi fa-in qātalūkum faqtulūhum ka-dhālika jazāʾu l-kāfirīna

And slay them wherever ye catch them, and turn them out from where they have Turned you out; for tumult and oppression are worse than slaughter; but fight them not at the Sacred Mosque, unless they (first) fight you there; but if they fight you, slay them. Such is the reward of those who suppress faith.

Sura Āl-ʿImrān 3:112

ضُرِبَتْ عَلَيْهِمُ ٱلذِّلَّةُ أَيْنَ مَا ثُقِفُوٓا۟ إِلَّا بِحَبْلٍ مِّنَ ٱللَّـهِ وَحَبْلٍ مِّنَ ٱلنَّاسِ وَبَآءُو بِغَضَبٍ مِّنَ ٱللَّـهِ وَضُرِبَتْ عَلَيْهِمُ ٱلْمَسْكَنَةُ ذَٰلِكَ بِأَنَّهُمْ كَانُوا۟ يَكْفُرُونَ بِـَٔايَٰتِ ٱللَّـهِ وَيَقْتُلُونَ ٱلْأَنۢبِيَآءَ بِغَيْرِ حَقٍّ ذَٰلِكَ بِمَا عَصَوا۟ وَّكَانُوا۟ يَعْتَدُونَ

ḍuribat ʿalayhimu l-dhillatu ayna mā thuqifū illā biḥablin mina allāhi wa-ḥablin mina l-nāsi wa-bāʾū bighaḍabin mina allāhi wa-ḍuribat ʿalayhimu l-maskanatu dhālika bi-annahum kānū yakfurūna bi-āyāti allāhi wa-yaqtulūna l-anbiyāʾa bi-ghayri ḥaqqin dhālika bi-mā ʿaṣaw wa-kānū yaʿtadūna

Shame is pitched over them (Like a tent) wherever they are found, except when under a covenant (of protection) from Allah and from men; they draw on themselves wrath from Allah, and pitched over them is (the tent of) destitution. This because they rejected the Signs of Allah, and slew the prophets in defiance of right; this because they rebelled and transgressed beyond bounds.

Sura al-Nisāʾ 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 وَأُو۟لَٰٓئِكُمْ جَعَلْنَا لَكُمْ عَلَيْهِمْ سُلْطَٰنًا مُّبِينًا

sa-tajidūna ākharīna yurīdūna an yaʾmanūkum wa-yaʾmanū qawmahum kulla mā ruddū ilā l-fitnati urkisū fīhā fa-in lam yaʿtazilūkum wa-yulqū ilaykumu l-salama wa-yakuffū aydiyahum fa-khudhūhum wa-aqtulūhum ḥaythu thaqiftumūhum wa-ūlāʾikum jaʿalnā la-kum ʿalayhim sulṭānan mubīnan

Others you will find that wish to gain your confidence as well as that of their people: Every time they are sent back to temptation, they succumb thereto: if they withdraw not from you nor give you (guarantees) of peace besides restraining their hands, seize them and slay them wherever ye get them: In their case We have provided you with a clear argument against them.

Sura al-Aḥzāb 33:61

مَّلْعُونِينَ أَيْنَمَا ثُقِفُوٓا۟ أُخِذُوا۟ وَقُتِّلُوا۟ تَقْتِيلًا

malʿūnīna aynamā thuqifū ukhidhū wa-quttilū taqtīlan

They shall have a curse on them: whenever they are found, they shall be seized and slain (without mercy).

Sura al-Mumtaḥanah 60:2

إِن يَثْقَفُوكُمْ يَكُونُوا۟ لَكُمْ أَعْدَآءً وَيَبْسُطُوٓا۟ إِلَيْكُمْ أَيْدِيَهُمْ وَأَلْسِنَتَهُم بِٱلسُّوٓءِ وَوَدُّوا۟ لَوْ تَكْفُرُونَ

in yathqafūkum yakūnū la-kum aʿdaʾan wa-yabsuṭū ilaykum aydiyahum wa-alsinatahum bil-sūʾi wa-waddū law takfurūna

If they were to get the better of you, they would behave to you as enemies, and stretch forth their hands and their tongues against you for evil: and they desire that ye should reject the Truth.
