Muhammad • EN-TAFSIR-IBN-ABBAS
﴿ 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.”
(Lo! those who disbelieve) in Muhammad (pbuh) and the Qur'an (and turn from the way of Allah) and bar people from the religion and obedience of Allah (and oppose the messenger) in relation to Religion (after the guidance) Allah's divine Oneness (hath been manifested unto them, they hurt Allah not a jot) they do not diminish Allah in any way, (and He will make their actions fruitless) He annuls their good works and whatever they have spent on the Day of Badr; this refers to those who fed the army of the disbelievers on the Day of Badr.
