Nullifying the Disbelievers' Deeds and the Command to chase Them

Allah then informs about those who disbelieve, obstruct others from the path of Allah, oppose the Messenger and contend with him, and revert from the faith after guidance has become clear to them. He indicates that those people can never harm Allah in the least, and rather they only harm themselves and become losers on the Day of Resurrection. He will nullify their deeds. Allah will not reward them even the weight of a mosquito (i.e., the smallest thing) for any good that they did before their apostasy, but would instead totally invalidate and destroy it. Their apostasy wipes away their good deeds entirely, just as the good deeds would normally wipe away the evil deeds. Imam Ahmad Ibn Nasr Al-Marwazi reported in Kitab As-Salah (the Book of Prayer) that Abu Al-`Aliyah said, "The Prophet's Companions used to think that no sin would harm a person who says `La ilaha illallah,' just as no good deed would benefit a person who joins partners with Allah. So Allah revealed,

أَطِيعُواْ اللَّهَ وَأَطِيعُواْ الرَّسُولَ وَلاَ تُبْطِلُواْ أَعْمَـلَكُمْ

Commentary

إِنَّ الَّذِينَ كَفَرُ‌وا وَصَدُّوا عَن سَبِيلِ اللَّـهِ (Those who disbelieve and prevent (others) from Allah's way ... - 47:32) This verse also refers to the hypocrites, and the Jewish tribes of Banu Quraizah and Banu Nadir. Sayyidna Ibn ` Abbas ؓ says that this verse refers to those hypocrites who, on the occasion of the battle of Badr, joined forces with the infidels of Quraysh and helped them in such a way that twelve men of the two tribes took upon themselves the responsibility of feeding the entire army. Each one of the twelve men took turns to organize meal for the enemy camp on different days.
