Surah Al-Anfal (The Spoils of War), Verse 37

لِیَمِیْزَ اللّٰهُ الْخَبِیْثَ مِنَ الطَّیِّبِ وَیَجْعَلَ الْخَبِیْثَ بَعْضَهٗ عَلٰی بَعْضٍ فَیَرْكُمَهٗ جَمِیْعًا فَیَجْعَلَهٗ فِیْ جَهَنَّمَ اُولٰٓىِٕكَ هُمُ الْخٰسِرُوْنَ 

Liyameezal laahul khabeesa minat taiyibi wa yaj'alal khabeesa ba'dahoo 'ala ba'din fayarkumahoo jamee'an fayaj'alahoo fee Jahannnam; ulaaa'ika humul khaasiroon

“In order that Allah may separate the impure from the pure, put the impure, one on another, heap them together, and cast them into Hell. They will be the ones to have lost.”
