﴿ 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.”

Indeed those who disbelieve and bar from the way of God the path of truth and defy the Messenger opposing him after the guidance this is the meaning of ‘the way of God’ has become clear to them they will not hurt God in any way and He will make their works fail He will invalidate them good works such as voluntary alms and the like and so they will not find any reward for it in the Hereafter — this was revealed either regarding those Meccan participants at the battle of Badr who provided food for the needy or regarding the Jewish tribes of Qurayza and al-Nadīr.
