مَا كَانَ لِنَبِىٍّ أَن يَكُونَ لَهُۥٓ أَسۡرَىٰ حَتَّىٰ يُثۡخِنَ فِى ٱلۡأَرۡضِ ۚ تُرِيدُونَ عَرَضَ ٱلدُّنۡيَا وَٱللَّهُ يُرِيدُ ٱلۡءَاخِرَةَ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ
It is not fitting for a prophet that he should have prisoners of war until he hath thoroughly subdued the land. Ye look for the temporal goods of this world; but Allah looketh to the Hereafter: And Allah is Exalted in might, Wise.<br/>
The following was revealed when they ransomed those taken captive at Badr: It is not for any Prophet to have (read as an takoona lahu or an yakoona lahu) prisoners until he has made slaughter in the land, going all the way in fighting disbelievers. You, O believers, desire the transient things of this world, its ephemeral gains, by ransoming, while God desires, for you, the Hereafter, that is, its reward, through your killing them; and God is Mighty, Wise: this was abrogated by His words [and set them free] afterward either with grace or by ransom [Q. 47:4].
