repentence of recent belligerents

إِلَّا ٱلَّذِينَ تَابُوا۟ مِن قَبْلِ أَن تَقْدِرُوا۟ عَلَيْهِمْ ۖ فَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

unless they repent before you overpower them- in that case bear in mind that God is forgiving and merciful.

فَإِذَا ٱنسَلَخَ ٱلْأَشْهُرُ ٱلْحُرُمُ فَٱقْتُلُوا۟ ٱلْمُشْرِكِينَ حَيْثُ وَجَدتُّمُوهُمْ وَخُذُوهُمْ وَٱحْصُرُوهُمْ وَٱقْعُدُوا۟ لَهُمْ كُلَّ مَرْصَدٍ ۚ فَإِن تَابُوا۟ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَءَاتَوُا۟ ٱلزَّكَوٰةَ فَخَلُّوا۟ سَبِيلَهُمْ ۚ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

When the [four] forbidden months are over, wherever you encounter the idolaters, kill them, seize them, besiege them, wait for them at every lookout post; but if they turn [to God], maintain the prayer, and pay the prescribed alms, let them go on their way, for God is most forgiving and merciful.

فَإِن تَابُوا۟ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَءَاتَوُا۟ ٱلزَّكَوٰةَ فَإِخْوَٰنُكُمْ فِى ٱلدِّينِ ۗ وَنُفَصِّلُ ٱلْـَٔايَـٰتِ لِقَوْمٍ يَعْلَمُونَ

If they turn to God, keep up the prayer, and pay the prescribed alms, then they are your brothers in faith: We make the messages clear for people who are willing to learn.
