Qur'an 4:90

إِلَّا ٱلَّذِينَ يَصِلُونَ إِلَىٰ قَوْمٍۭ بَيْنَكُمْ وَبَيْنَهُم مِّيثَـٰقٌ أَوْ جَآءُوكُمْ حَصِرَتْ صُدُورُهُمْ أَن يُقَـٰتِلُوكُمْ أَوْ يُقَـٰتِلُوا۟ قَوْمَهُمْ ۚ وَلَوْ شَآءَ ٱللَّهُ لَسَلَّطَهُمْ عَلَيْكُمْ فَلَقَـٰتَلُوكُمْ ۚ فَإِنِ ٱعْتَزَلُوكُمْ فَلَمْ يُقَـٰتِلُوكُمْ وَأَلْقَوْا۟ إِلَيْكُمُ ٱلسَّلَمَ فَمَا جَعَلَ ٱللَّهُ لَكُمْ عَلَيْهِمْ 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 Allāh 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 Allāh has not made for you a cause [for fighting] against them.”
