The Quran root ق ت ل q-t-l

وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِ يَا قَوْمِ إِنَّكُمْ ظَلَمْتُمْ أَنفُسَكُم بِاتِّخَاذِكُمُ الْعِجْلَ فَتُوبُوا إِلَىٰ بَارِئِكُمْ فَاقْتُلُوا أَنفُسَكُمْ ذَٰلِكُمْ خَيْرٌ لَّكُمْ عِندَ بَارِئِكُمْ فَتَابَ عَلَيْكُمْ إِنَّهُ هُوَ التَّوَّابُ الرَّحِيمُ ٥٤

فَاقْتُلُوا fa-uq'tulū · and kill

And [recall] when Moses said to his people, "O my people, indeed you have wronged yourselves by your taking of the calf [for worship]. So repent to your Creator and kill yourselves [i.e., the guilty among you]. That is best for [all of] you in the sight of your Creator." Then He accepted your repentance; indeed, He is the Accepting of Repentance, the Merciful. (Surah Al-Baqarah, 2:54)

وَإِذْ قُلْتُمْ يَا مُوسَىٰ لَن نَّصْبِرَ عَلَىٰ طَعَامٍ وَاحِدٍ فَادْعُ لَنَا رَبَّكَ يُخْرِجْ لَنَا مِمَّا تُنبِتُ الْأَرْضُ مِن بَقْلِهَا وَقِثَّائِهَا وَفُومِهَا وَعَدَسِهَا وَبَصَلِهَا قَالَ أَتَسْتَبْدِلُونَ الَّذِي هُوَ أَدْنَىٰ بِالَّذِي هُوَ خَيْرٌ اهْبِطُوا مِصْرًا فَإِنَّ لَكُم مَّا سَأَلْتُمْ وَضُرِبَتْ عَلَيْهِمُ الذِّلَّةُ وَالْمَسْكَنَةُ وَبَاءُوا بِغَضَبٍ مِّنَ اللَّهِ ذَٰلِكَ بِأَنَّهُمْ كَانُوا يَكْفُرُونَ بِآيَاتِ اللَّهِ وَيَقْتُلُونَ النَّبِيِّينَ بِغَيْرِ الْحَقِّ ذَٰلِكَ بِمَا عَصَوا وَّكَانُوا يَعْتَدُونَ ٦١

وَيَقْتُلُونَ wayaqtulūna · and kill

And [recall] when you said, "O Moses, we can never endure one [kind of] food. So call upon your Lord to bring forth for us from the earth its green herbs and its cucumbers and its garlic and its lentils and its onions." [Moses] said, "Would you exchange what is better for what is less? Go into [any] settlement and indeed, you will have what you have asked." And they were covered with humiliation and poverty and returned with anger from Allāh [upon them]. That was because they [repeatedly] disbelieved in the signs of Allāh and killed the prophets without right. That was because they disobeyed and were [habitually] transgressing. (Surah Al-Baqarah, 2:61)

وَقَاتِلُوا فِي سَبِيلِ اللَّهِ الَّذِينَ يُقَاتِلُونَكُمْ وَلَا تَعْتَدُوا إِنَّ اللَّهَ لَا يُحِبُّ الْمُعْتَدِينَ ١٩٠

وَقَاتِلُوا waqātilū · And fight

Fight in the way of Allāh those who fight against you but do not transgress. Indeed, Allāh does not like transgressors. (Surah Al-Baqarah, 2:190)

كُتِبَ عَلَيْكُمُ الْقِتَالُ وَهُوَ كُرْهٌ لَّكُمْ وَعَسَىٰ أَن تَكْرَهُوا شَيْئًا وَهُوَ خَيْرٌ لَّكُمْ وَعَسَىٰ أَن تُحِبُّوا شَيْئًا وَهُوَ شَرٌّ لَّكُمْ وَاللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ ٢١٦

الْقِتَالُ l-qitālu · [the] fighting

Battle has been enjoined upon you while it is hateful to you. But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allāh knows, while you know not. (Surah Al-Baqarah, 2:216)

وَاقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُم مِّنْ حَيْثُ أَخْرَجُوكُمْ وَالْفِتْنَةُ أَشَدُّ مِنَ الْقَتْلِ وَلَا تُقَاتِلُوهُمْ عِندَ الْمَسْجِدِ الْحَرَامِ حَتَّىٰ يُقَاتِلُوكُمْ فِيهِ فَإِن قَاتَلُوكُمْ فَاقْتُلُوهُمْ كَذَٰلِكَ جَزَاءُ الْكَافِرِينَ ١٩١

الْقَتْلِ l-qatli · [the] killing

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. (Surah Al-Baqarah, 2:191)

تِلْكَ الرُّسُلُ فَضَّلْنَا بَعْضَهُمْ عَلَىٰ بَعْضٍ مِّنْهُم مَّن كَلَّمَ اللَّهُ وَرَفَعَ بَعْضَهُمْ دَرَجَاتٍ وَآتَيْنَا عِيسَى ابْنَ مَرْيَمَ الْبَيِّنَاتِ وَأَيَّدْنَاهُ بِرُوحِ الْقُدُسِ وَلَوْ شَاءَ اللَّهُ مَا اقْتَتَلَ الَّذِينَ مِن بَعْدِهِم مِّن بَعْدِ مَا جَاءَتْهُمُ الْبَيِّنَاتُ وَلَٰكِنِ اخْتَلَفُوا فَمِنْهُم مَّنْ آمَنَ وَمِنْهُم مَّن كَفَرَ وَلَوْ شَاءَ اللَّهُ مَا اقْتَتَلُوا وَلَٰكِنَّ اللَّهَ يَفْعَلُ مَا يُرِيدُ ٢٥٣

اقْتَتَلَ iq'tatala · (would have) fought each other

Those messengers - some of them We caused to exceed others. Among them were those to whom Allāh spoke, and He raised some of them in degree. And We gave Jesus, the son of Mary, clear proofs, and We supported him with the Pure Spirit [i.e., Gabriel]. If Allāh had willed, those [generations] succeeding them would not have fought each other after the clear proofs had come to them. But they differed, and some of them believed and some of them disbelieved. And if Allāh had willed, they would not have fought each other, but Allāh does what He intends. (Surah Al-Baqarah, 2:253)
