Fussilat 41:27

فَلَنُذِيقَنَّ ٱلَّذِينَ كَفَرُوا۟ عَذَابًا شَدِيدًا وَلَنَجْزِيَنَّهُمْ أَسْوَأَ ٱلَّذِى كَانُوا۟ يَعْمَلُونَ

Falanudhīqanna alladhīna kafarū ʿadhāban shadīdan walanajziyannahum aswa-a alladhī kānū yaʿmalūna

But We will surely cause those who disbelieve to taste a severe punishment, and We will surely recompense them for the worst of what they had been doing.
