quran:41:27

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.  

God, exalted be He, says regarding them: But verily We will make those who disbelieve taste a severe chastisement, and We will verily requite them the worst of what they used to do, in other words, ˹with˺ the worst requital for their deeds.
القرآن:٤١:٢٧

فَلَنُذِيقَنَّ الَّذِينَ كَفَرُوا عَذَابًا شَدِيدًا وَلَنَجْزِيَنَّهُمْ أَسْوَأَ الَّذِي كَانُوا يَعْمَلُونَ  

قال الله تعالى فيهم: {فلنذيقنَّ الذين كفروا عذاباً شديداً ولنجزينهم أسوأ الذي كانوا يعملون} أي أقبح جزاء عملهم.
