﴿ إِنَّ ٱلَّذِينَ كَفَرُوا۟ وَمَاتُوا۟ وَهُمْ كُفَّارٌ أُو۟لَٰٓئِكَ عَلَيْهِمْ لَعْنَةُ ٱللَّهِ وَٱلْمَلَٰٓئِكَةِ وَٱلنَّاسِ أَجْمَعِينَ ﴾

“Behold, as for those who are bent on denying the truth and die as deniers of the truth -their due is rejection by God, and by the angels,, and by all [righteous] men.”

(Lo! Those who disbelieve, and die while they are disbelievers) in Allah and His Messenger; (on them is the curse of Allah) the torment of Allah (and of the angels) the curse of the angels (and of men combined) the curses directed by believers towards each other will end up as curses on these unbelievers.
