Allah says:

[تَرَى الظَّـلِمِينَ مُشْفِقِينَ مِمَّا كَسَبُواْ]

(You will see the wrongdoers fearful of that which they have earned,) means, in the arena of Resurrection.

[وَهُوَ وَاقِعٌ بِهِمْ]

(and it will surely befall them.) means, the thing that they fear will undoubtedly happen to them. This is how they will be on the Day of Resurrection; they will be in a state of utter fear and terror.

[وَالَّذِينَ ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَـتِ فِى رَوْضَـتِ الْجَنَّـتِ لَهُمْ مَّا يَشَآءُونَ عِندَ رَبِّهِمْ]

(But those who believe and do righteous deeds (will be) in the flowering meadows of the Gardens. They shall have whatsoever they desire with their Lord.) What comparison can there be between the former and the latter How can the one who will be in the arena of resurrection in a state of humiliation and fear, deserving it for his wrongdoing, be compared with the one who will be in the gardens of Paradise, enjoying whatever he wants of food, drink, clothing, dwellings, scenery, spouses and other delights such as no eye has seen, no ear has heard, and has never crossed the minds of men. Allah says:

[ذَلِكَ هُوَ الْفَضْلُ الْكَبِيرُ]

(That is the supreme grace.) means, the ultimate victory and complete blessing.

[ذَلِكَ الَّذِى يُبَشِّرُ اللَّهُ عِبَادَهُ الَّذِينَ ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَـتِ قُل لاَّ أَسْـَلُكُمْ عَلَيْهِ أَجْراً إِلاَّ الْمَوَدَّةَ فِى الْقُرْبَى وَمَن يَقْتَرِفْ حَسَنَةً نَّزِدْ لَهُ فِيهَا حُسْناً إِنَّ اللَّهَ غَفُورٌ شَكُورٌ - أَمْ يَقُولُونَ افْتَرَى عَلَى اللَّهِ كَذِباً فَإِن يَشَإِ اللَّهُ يَخْتِمْ عَلَى قَلْبِكَ وَيَمْحُ اللَّهُ الْبَـطِلَ وَيُحِقُّ الْحَقَّ بِكَلِمَـتِهِ إِنَّهُ عَلِيمٌ بِذَاتِ الصُّدُورِ ]

(23. That is whereof Allah gives glad tidings to His servants who believe and do righteous good deeds. Say: "No reward do I ask of you for this except to be kind to me for my kinship with you.'' And whoever earns a good righteous deed, We shall give him an increase of good in respect thereof. Verily, Allah is Oft-Forgiving, Most Ready to appreciate.) (24. Or say they: "He has invented a lie against Allah'' If Allah willed, He could have sealed up your heart. And Allah wipes out falsehood, and establishes the truth by His Word. Verily, He knows well what are in the breasts.)
