Quran Muhammad 47:34

إِنَّ ٱلَّذِينَ كَفَرُواْ وَصَدُّواْ عَن سَبِيلِ ٱللَّهِ ثُمَّ مَاتُواْ وَهُمۡ كُفَّارٞ فَلَن يَغۡفِرَ ٱللَّهُ لَهُمۡ

Translation

Indeed, those who disbelieved and averted [people] from the path of Allāh and then died while they were disbelievers - never will Allāh forgive them.
