Quran 47:34 — Muhammad (Muhammad)

إِنَّ الَّذينَ كَفَروا وَصَدّوا عَن سَبيلِ اللَّهِ ثُمَّ ماتوا وَهُم كُفّارٌ فَلَن يَغفِرَ اللَّهُ لَهُم

Those who disbelieve and repel from the path of GOD, then die as disbelievers, GOD will never forgive them.

[47:33] O you who believe, you shall obey GOD, and obey the messenger. Otherwise, all your works will be in vain.

[47:35] Therefore, you shall not waver and surrender in pursuit of peace, for you are guaranteed victory, and GOD is with you. He will never waste your efforts.
