18:16
وَ إِذِ ٱعْتَزَلْ تُمُو هُمْ وَ مَا يَعْبُدُ ونَ إِلَّا ٱللَّهَ فَ أْوُ ۥٓا۟ إِلَى ٱلْ كَهْفِ يَنشُرْ لَ كُمْ رَبُّ كُم مِّن رَّحْمَتِ هِۦ وَ يُهَيِّئْ لَ كُم مِّنْ أَمْرِ كُم مِّرْفَقًا
[The youths said to one another], "And when you have withdrawn from them and that which they worship other than Allah, retreat to the cave. Your Lord will spread out for you of His mercy and will prepare for you from your affair facility."
19:48
وَ أَعْتَزِلُ كُمْ وَ مَا تَدْعُ ونَ مِن دُونِ ٱللَّهِ وَ أَدْعُوا۟ رَبِّ ى عَسَىٰٓ أَ لَّآ أَكُونَ بِ دُعَآءِ رَبِّ ى شَقِيًّا
And I will leave you and those you invoke other than Allah and will invoke my Lord. I expect that I will not be in invocation to my Lord unhappy."
19:49
فَ لَمَّا ٱعْتَزَلَ هُمْ وَ مَا يَعْبُدُ ونَ مِن دُونِ ٱللَّهِ وَهَبْ نَا لَ هُۥٓ إِسْحَٰقَ وَ يَعْقُوبَ وَ كُلًّا جَعَلْ نَا نَبِيًّا
So when he had left them and those they worshipped other than Allah, We gave him Isaac and Jacob, and each [of them] We made a prophet.
2:222
وَ يَسْـَٔلُ ونَ كَ عَنِ ٱلْ مَحِيضِ قُلْ هُوَ أَذًى فَ ٱعْتَزِلُ وا۟ ٱل نِّسَآءَ فِى ٱلْ مَحِيضِ وَ لَا تَقْرَبُ و هُنَّ حَتَّىٰ يَطْهُرْ نَ فَ إِذَا تَطَهَّرْ نَ فَ أْتُ و هُنَّ مِنْ حَيْثُ أَمَرَ كُمُ ٱللَّهُ إِنَّ ٱللَّهَ يُحِبُّ ٱل تَّوَّٰبِينَ وَ يُحِبُّ ٱلْ مُتَطَهِّرِينَ
And they ask you about menstruation. Say, "It is harm, so keep away from wives during menstruation. And do not approach them until they are pure. And when they have purified themselves, then come to them from where Allah has ordained for you. Indeed, Allah loves those who are constantly repentant and loves those who purify themselves."
44:21
وَ إِن لَّمْ تُؤْمِنُ وا۟ لِ ى فَ ٱعْتَزِلُ و نِ
But if you do not believe me, then leave me alone."
4:90
إِلَّا ٱلَّذِينَ يَصِلُ ونَ إِلَىٰ قَوْمٍۭ بَيْنَ كُمْ وَ بَيْنَ هُم مِّيثَٰقٌ أَوْ جَآءُ و كُمْ حَصِرَتْ صُدُورُ هُمْ أَن يُقَٰتِلُ و كُمْ أَوْ يُقَٰتِلُ وا۟ قَوْمَ هُمْ وَ لَوْ شَآءَ ٱللَّهُ لَ سَلَّطَ هُمْ عَلَيْ كُمْ فَ لَ قَٰتَلُ و كُمْ فَ إِنِ ٱعْتَزَلُ و كُمْ فَ لَمْ يُقَٰتِلُ و كُمْ وَ أَلْقَ وْا۟ إِلَيْ كُمُ ٱل سَّلَمَ فَ مَا جَعَلَ ٱللَّهُ لَ كُمْ عَلَيْ هِمْ سَبِيلًا
Except for those who take refuge with a people between yourselves and whom is a treaty or those who come to you, their hearts strained at [the prospect of] fighting you or fighting their own people. And if Allah had willed, He could have given them power over you, and they would have fought you. So if they remove themselves from you and do not fight you and offer you peace, then Allah has not made for you a cause [for fighting] against them.
4:91
سَ تَجِدُ ونَ ءَاخَرِينَ يُرِيدُ ونَ أَن يَأْمَنُ و كُمْ وَ يَأْمَنُ وا۟ قَوْمَ هُمْ كُلَّ مَا رُدُّ وٓا۟ إِلَى ٱلْ فِتْنَةِ أُرْكِسُ وا۟ فِي هَا فَ إِن لَّمْ يَعْتَزِلُ و كُمْ وَ يُلْقُ وٓا۟ إِلَيْ كُمُ ٱل سَّلَمَ وَ يَكُفُّ وٓا۟ أَيْدِيَ هُمْ فَ خُذُ و هُمْ وَ ٱقْتُلُ و هُمْ حَيْثُ ثَقِفْ تُمُو هُمْ وَ أُو۟لَٰٓئِكُمْ جَعَلْ نَا لَ كُمْ عَلَيْ هِمْ سُلْطَٰنًا مُّبِينًا
You will find others who wish to obtain security from you and [to] obtain security from their people. Every time they are returned to [the influence of] disbelief, they fall back into it. So if they do not withdraw from you or offer you peace or restrain their hands, then seize them and kill them wherever you overtake them. And those - We have made for you against them a clear authorization.
