Surah Muhammad, Verse 34
إِنَّ ٱلَّذِينَ كَفَرُوا۟ وَصَدُّوا۟ عَن سَبِيلِ ٱللَّهِ ثُمَّ مَاتُوا۟ وَهُمْ كُفَّارٌۭ فَلَن يَغْفِرَ ٱللَّهُ لَهُمْ
Translation — Sahih International
Indeed, those who disbelieved and averted [people] from the path of Allah and then died while they were disbelievers - never will Allah forgive them.
