أُو۟لَٰٓئِكَ ٱلَّذِينَ لَيْسَ لَهُمْ فِى ٱلْءَاخِرَةِ إِلَّا ٱلنَّارُ ۖ وَحَبِطَ مَا صَنَعُوا۟ فِيهَا وَبَٰطِلٌۭ مَّا كَانُوا۟ يَعْمَلُونَ
Those are they for whom is naught in the Hereafter save the Fire. (All) that they contrive here is vain and (all) that they are wont to do is fruitless.
Surah Hud(11:16)
