وَٱلَّذِينَ كَسَبُوا۟ ٱلسَّيِّـَٔاتِ جَزَآءُ سَيِّئَةٍۭ بِمِثْلِهَا وَتَرْهَقُهُمْ ذِلَّةٌۭ ۖ مَّا لَهُم مِّنَ ٱللَّهِ مِنْ عَاصِمٍۢ ۖ كَأَنَّمَآ أُغْشِيَتْ وُجُوهُهُمْ قِطَعًۭا مِّنَ ٱلَّيْلِ مُظْلِمًا ۚ أُو۟لَٰٓئِكَ أَصْحَٰبُ ٱلنَّارِ ۖ هُمْ فِيهَا خَٰلِدُونَ
And those who earn ill-deeds, (for them) requital of each ill-deed by the like thereof; and ignominy overtaketh them - They have no protector from Allah - as if their faces had been covered with a cloak of darkest night. Such are rightful owners of the Fire; they will abide therein.
Surah Yunus(10:27)
