Moral distinction between good and evil

لِيَمِيزَ ٱللَّهُ ٱلْخَبِيثَ مِنَ ٱلطَّيِّبِ وَيَجْعَلَ ٱلْخَبِيثَ بَعْضَهُۥ عَلَىٰ بَعْضٍ فَيَرْكُمَهُۥ جَمِيعًا فَيَجْعَلَهُۥ فِى جَهَنَّمَ ۚ أُو۟لَـٰٓئِكَ هُمُ ٱلْخَـٰسِرُونَ

[It is] so that Allāh 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.
