Qur'an 8:67

مَا كَانَ لِنَبِىٍّ أَن يَكُونَ لَهُۥٓ أَسْرَىٰ حَتَّىٰ يُثْخِنَ فِى ٱلْأَرْضِ ۚ تُرِيدُونَ عَرَضَ ٱلدُّنْيَا وَٱللَّهُ يُرِيدُ ٱلْـَٔاخِرَةَ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ

“It is not for a prophet to have captives [of war] until he inflicts a massacre [upon Allāh's enemies] in the land. You [i.e., some Muslims] desire the commodities of this world, but Allāh desires [for you] the Hereafter. And Allāh is Exalted in Might and Wise.”
