Tafsir Ibn Kathir -> Surah Fatir -> The Punishment of the Disbeliever and the Reward of the Believer on the Day of Resurrection

Having stated that the ultimate destiny of the followers of Iblis will be the blazing Fire, Allah then tells us that for those who disbelieve there will be a severe punishment. This is because they obeyed the Shaytan and disobeyed Ar-Rahman. And He tells us that those who believed in Allah and His Messengers

﴿وَعَمِلُواْ الصَّـلِحَـتِ لَهُم مَّغْفِرَةٌ﴾

(and do righteous good deeds, theirs will be forgiveness) meaning, from whatever sins they did,

﴿وَأَجْرٌ كَبِيرٌ﴾

and a great reward. for the good deeds that they did. Then Alla0h says:

﴿أَفَمَن زُيِّنَ لَهُ سُوءَ عَمَلِهِ فَرَءَاهُ حَسَناً﴾

(Is he, then, to whom the evil of his deeds is made fairseeming, so that he considers it as good) meaning, `such as disbelievers or immoral persons who do evil deeds and believe that they are doing something good, i.e., a person who is like that has been misguided by Allah, so what can you do for him You cannot help him at all.'

﴿فَإِنَّ اللَّهَ يُضِلُّ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ﴾

(Verily, Allah sends astray whom He wills and guides whom He wills.) means according to His decree.

﴿فَلاَ تَذْهَبْ نَفْسُكَ عَلَيْهِمْ حَسَرَتٍ﴾

(So destroy not yourself in sorrow for them. ) means, do not grieve about that, for Allah is Wise in His decree and He leaves astray whomsoever He leaves astray, and He guides whomsoever He guides, and in doing so He has perfect knowledge and wisdom. Allah says:

﴿إِنَّ اللَّهَ عَلِيمٌ بِمَا يَصْنَعُونَ﴾

(Truly, Allah is the All-Knower of what they do!)

﴿وَاللَّهُ الَّذِى أَرْسَلَ الرِّيَاحَ فَتُثِيرُ سَحَـباً فَسُقْنَاهُ إِلَى بَلَدٍ مَّيِّتٍ فَأَحْيَيْنَا بِهِ الاٌّرْضَ بَعْدَ مَوْتِهَا كَذَلِكَ النُّشُورُ - مَن كَانَ يُرِيدُ الْعِزَّةَ فَلِلَّهِ الْعِزَّةُ جَمِيعاً إِلَيْهِ يَصْعَدُ الْكَلِمُ الطَّيِّبُ وَالْعَمَلُ الصَّـلِحُ يَرْفَعُهُ وَالَّذِينَ يَمْكُرُونَ السَّيِّئَاتِ لَهُمْ عَذَابٌ شَدِيدٌ وَمَكْرُ أُوْلَـئِكَ هُوَ يَبُورُ - وَاللَّهُ خَلَقَكُمْ مِّن تُرَابٍ ثُمَّ مِن نُّطْفَةٍ ثُمَّ جَعَلَكُمْ أَزْوَجاً وَمَا تَحْمِلُ مِنْ أُنْثَى وَلاَ تَضَعُ إِلاَّ بِعِلْمِهِ وَمَا يُعَمَّرُ مِن مُّعَمَّرٍ وَلاَ يُنقَصُ مِنْ عُمُرِهِ إِلاَّ فِى كِتَـبٍ إِنَّ ذَلِكَ عَلَى اللَّهِ يَسِيرٌ ﴾

(9. And it is Allah Who sends the winds, so that they raise up the clouds, and We drive them to a dead land, and revive therewith the earth after its death. As such (will be) the Resurrection!) (10. Whosoever desires Al-`Izzah then to Allah belongs Al-`Izzah. To Him ascend the good words, and the righteous deeds exalt it, but those who plot evils, theirs will be a severe torment. And the plotting of such will perish.) (11. And Allah did create you from dust, then from Nutfah, then He made you pairs. And no female conceives or gives birth but with His knowledge. And no aged man is granted a length of life nor is a part cut off from his life, but is in a Book. Surely, that is easy for Allah.)
