﴿ إِنَّ ٱلَّذِينَ كَفَرُوا۟ وَصَدُّوا۟ عَن سَبِيلِ ٱللَّهِ وَشَآقُّوا۟ ٱلرَّسُولَ مِنۢ بَعْدِ مَا تَبَيَّنَ لَهُمُ ٱلْهُدَىٰ لَن يَضُرُّوا۟ ٱللَّهَ شَيْـًۭٔا وَسَيُحْبِطُ أَعْمَٰلَهُمْ ﴾

“Verily, they who are bent on denying the truth and on barring [others] from the path of God, and [who thus] cut themselves off from the Apostle after guidance has been vouchsafed to them, can in no wise harm God; but He will cause all their deeds to come to nought.”
