فَإِمَّا تَثْقَفَنَّهُمْ فِى ٱلْحَرْبِ فَشَرِّدْ بِهِم مَّنْ خَلْفَهُمْ لَعَلَّهُمْ يَذَّكَّرُونَ

إِنَّ شَرَّ ٱلدَّوَآبِّ عِندَ ٱللَّهِ ٱلَّذِينَ كَفَرُوا۟ فَهُمْ لَا يُؤْمِنُونَ
Indeed, the worst of living creatures in the sight of Allah are those who have disbelieved, and they will not [ever] believe -
ٱلَّذِينَ عَـٰهَدتَّ مِنْهُمْ ثُمَّ يَنقُضُونَ عَهْدَهُمْ فِى كُلِّ مَرَّةٍ وَهُمْ لَا يَتَّقُونَ
The ones with whom you made a treaty but then they break their pledge every time, and they do not fear Allah.
وَإِمَّا تَخَافَنَّ مِن قَوْمٍ خِيَانَةً فَٱنۢبِذْ إِلَيْهِمْ عَلَىٰ سَوَآءٍ ۚ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْخَآئِنِينَ
If you [have reason to] fear from a people betrayal, throw [their treaty] back to them, [putting you] on equal terms. Indeed, Allah does not like traitors.
وَلَا يَحْسَبَنَّ ٱلَّذِينَ كَفَرُوا۟ سَبَقُوٓا۟ ۚ إِنَّهُمْ لَا يُعْجِزُونَ
And let not those who disbelieve think they will escape. Indeed, they will not cause failure [to Allah].
