Surah 27. An-Naml
Ayah 87 - 90
87وَيَوْمَ يُنفَخُ فِى ٱلصُّورِ فَفَزِعَ مَن فِى ٱلسَّمَـٰوَٰتِ وَمَن فِى ٱلْأَرْضِ إِلَّا مَن شَآءَ ٱللَّهُ ۚ وَكُلٌّ أَتَوْهُ دَٰخِرِينَ
88وَتَرَى ٱلْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِىَ تَمُرُّ مَرَّ ٱلسَّحَابِ ۚ صُنْعَ ٱللَّهِ ٱلَّذِىٓ أَتْقَنَ كُلَّ شَىْءٍ ۚ إِنَّهُۥ خَبِيرٌۢ بِمَا تَفْعَلُونَ
89مَن جَآءَ بِٱلْحَسَنَةِ فَلَهُۥ خَيْرٌ مِّنْهَا وَهُم مِّن فَزَعٍ يَوْمَئِذٍ ءَامِنُونَ
90وَمَن جَآءَ بِٱلسَّيِّئَةِ فَكُبَّتْ وُجُوهُهُمْ فِى ٱلنَّارِ هَلْ تُجْزَوْنَ إِلَّا مَا كُنتُمْ تَعْمَلُونَ
[87-90] And on the Day when the Trumpet will be blown, all those who are in the heavens and the earth, shall be struck with terror106 except those whom Allah shall be pleased to protect.-And all shall present themselves before Him in submission. Today, you see the mountains and think that they are firmly set, but on that Day they will be flying about like the clouds; this will be a manifestation of the powers of Allah, Who has ordered everything with wisdom. He is fully aware of what you do.107 He who will bring good deeds, will have a reward better than that,108 and such people shall be secure from the terror of that Day.109 And the one who will come with evil deeds, all such people shall be flung upon their faces into the Fire. Can you be rewarded except in accordance with your deeds?109a
106For a detailed discussion of the blowing of the Trumpet, see E.N. 47 of AI-An`am, E.N. 57 of Ibrahim, E.N. 78 of Ta Ha, E.N. 1 of Al-Hajj, E.N.'s. 46, 47 of Ya Sin and E.N. 79 of Az-Zumar.
107That is, "From such God you should not expect that after giving you the powers of intellect and discrimination and control over things, He will remain unaware of your deeds and actions and will not see how you have been using the delegated authority in the earth."
108The reward will be better in two ways: (1) It will be higher than what a person will actually deserve for his good deeds; and (2) it will be everlasting and for ever though the good act was temporary and its influence confined to a limited period only.
109That is, "Though the terrors of Resurrection will stun and confound the disbelievers, the believers will remain safe and secure from them, for everything in the Hereafter will be according to their expectations. They had already known from the messages brought by the Messengers of Allah that Resurrection will take place, and a new World will be established when everyone will be called to account for his deeds. Therefore, they will neither be bewildered nor alarmed, which will be the case with those who had denied this Day and retrained heedless of it, till their last breath in the world .They will also be satisfied because they had worked for this Day and had brought necessary provisions from the world for their success here. Therefore, they will not be stupefied and confounded as will be those who had invested all their energies and capabilities 'in their struggle for achieving worldly successes only, and had never thought that there would be life hereafter also for which they should make some provision. Contrary to them, the believers will be satisfied that the Day for the sake of which they had given up the unlawful benefits and pleasures of life and had undergone hardships and toil, had at last come, and they will not be deprived of the rewards of their works."
109aAt several places in the Qur'an it has been stated clearly that an evil will be punished in the Hereafter only to the extent of the evil committed, but a good act will be rewarded much more generously by Allah than what the doer will actually deserve for it. For more examples of this, see Surah Yunus: 26-27, AlQasas: 84. Al-'Ankabut: 7, Saba': 37-38, Al-Mu'min: 40.
