وَإِن يُرِيدُوا۟ خِيَانَتَكَ فَقَدْ خَانُوا۟ ٱللَّهَ مِن قَبْلُ فَأَمْكَنَ مِنْهُمْ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌ
But if they intend to betray you - then they have already betrayed Allah before, and He empowered [you] over them. And Allah is Knowing and Wise.
And if they the captives desire to betray you through words which they speak to you they have betrayed God before before Badr through unbelief; but He has given you power over them at Badr through slaying and capture so let them anticipate the like if they return to betrayal; and God is Knower of His creatures Wise in His actions.
