AL ANFAAL — Ayat 37

لِيَمِيزَ اللّهُ الْخَبِيثَ مِنَ الطَّيِّبِ وَيَجْعَلَ الْخَبِيثَ بَعْضَهُ عَلَىَ بَعْضٍ فَيَرْكُمَهُ جَمِيعاً فَيَجْعَلَهُ فِي جَهَنَّمَ أُوْلَـئِكَ هُمُ الْخَاسِرُونَ

[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.
