Al-Anfal 8:67

مَا كَانَ لِنَبِيٍّ أَن يَكُونَ لَهُۥٓ أَسۡرَىٰ حَتَّىٰ يُثۡخِنَ فِي ٱلۡأَرۡضِۚ تُرِيدُونَ عَرَضَ ٱلدُّنۡيَا وَٱللَّهُ يُرِيدُ ٱلۡأٓخِرَةَۗ وَٱللَّهُ عَزِيزٌ حَكِيمࣱ‏۝٦٧

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