لِيَميزَ اللَّهُ الخَبيثَ مِنَ الطَّيِّبِ وَيَجعَلَ الخَبيثَ بَعضَهُ عَلىٰ بَعضٍ فَيَركُمَهُ جَميعًا فَيَجعَلَهُ في جَهَنَّمَ ۚ أُولـٰئِكَ هُمُ الخاسِرونَ

[This is] so that Allah may distinguish the wicked from the good and place the wicked some of them upon others and heap them all together and put them into Hell. It is those who are the losers.
