مَا كَانَ لِنَبِيٍّ اَنْ يَّكُوْنَ لَهٗٓ اَسْرٰي حَتّٰي يُثْخِنَ فِي الْاَرْضِؕ تُرِيْدُوْنَ عَرَضَ الدُّنْيَاࣗۖ وَاللّٰهُ يُرِيْدُ الْاٰخِرَةَؕ وَاللّٰهُ عَزِيْزٌ حَكِيْمٌ ٦٧
Translation
A prophet may not take captives until he has thoroughly decimated [the enemy] in the land. You desire the transitory gains of this world, while Allah desires [for you] [the reward of] the Hereafter, and Allah is all-mighty, all-wise.
