وَقَاتِلُوا فِي سَبِيلِ اللَّهِ الَّذِينَ يُقَاتِلُونَكُمْ وَلَا تَعْتَدُوا ۚ إِنَّ اللَّهَ لَا يُحِبُّ الْمُعْتَدِينَ ١٩٠
Fight in the cause of Allah those who fight you, but do not transgress limits; for Allah loveth not transgressors.
2:191
وَاقْتُلُوهُمْ حَيْثُ ثَقِفْتُمُوهُمْ وَأَخْرِجُوهُمْ مِنْ حَيْثُ أَخْرَجُوكُمْ ۚ وَالْفِتْنَةُ أَشَدُّ مِنَ الْقَتْلِ ۚ وَلَا تُقَاتِلُوهُمْ عِنْدَ الْمَسْجِدِ الْحَرَامِ حَتَّىٰ يُقَاتِلُوكُمْ فِيهِ ۖ فَإِنْ قَاتَلُوكُمْ فَاقْتُلُوهُمْ ۗ كَذَٰلِكَ جَزَاءُ الْكَافِرِينَ ١٩١
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.
2:192
فَإِنِ انْتَهَوْا فَإِنَّ اللَّهَ غَفُورٌ رَحِيمٌ ١٩٢
But if they cease, Allah is Oft-forgiving, Most Merciful.
2:193
وَقَاتِلُوهُمْ حَتَّىٰ لَا تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ لِلَّهِ ۖ فَإِنِ انْتَهَوْا فَلَا عُدْوَانَ إِلَّا عَلَى الظَّالِمِينَ ١٩٣
And fight them on until there is no more Tumult or oppression, and there prevail justice and faith in Allah; but if they cease, Let there be no hostility except to those who practise oppression.
2:194
الشَّهْرُ الْحَرَامُ بِالشَّهْرِ الْحَرَامِ وَالْحُرُمَاتُ قِصَاصٌ ۚ فَمَنِ اعْتَدَىٰ عَلَيْكُمْ فَاعْتَدُوا عَلَيْهِ بِمِثْلِ مَا اعْتَدَىٰ عَلَيْكُمْ ۚ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّ اللَّهَ مَعَ الْمُتَّقِينَ ١٩٤
The prohibited month for the prohibited month,- and so for all things prohibited,- there is the law of equality. If then any one transgresses the prohibition against you, Transgress ye likewise against him. But fear Allah, and know that Allah is with those who restrain themselves.
