Allah said:

[أَمْ حَسِبَ الَّذِينَ يَعْمَلُونَ السَّيِّئَاتِ أَن يَسْبِقُونَا سَآءَ مَا يَحْكُمُونَ ]

(Or think those who do evil deeds that they can outstrip Us Evil is that which they judge!) means, those who are not believers should not think that they will escape such trials and tests, for ahead of them lies a greater and more severe punishment. Allah says:

[أَمْ حَسِبَ الَّذِينَ يَعْمَلُونَ السَّيِّئَاتِ أَن يَسْبِقُونَا]

(Or think those who do evil deeds that they can outstrip Us) meaning, "escape'' from Us.

[سَآءَ مَا يَحْكُمُونَ]

(Evil is that which they judge!) what they think is evil.

[مَن كَانَ يَرْجُو لِقَآءَ اللَّهِ فَإِنَّ أَجَلَ اللَّهِ لآتٍ وَهُوَ السَّمِيعُ الْعَلِيمُ - وَمَن جَاهَدَ فَإِنَّمَا يُجَـهِدُ لِنَفْسِهِ إِنَّ اللَّهَ لَغَنِىٌّ عَنِ الْعَـلَمِينَ - وَالَّذِينَ ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَـتِ لَنُكَفِّرَنَّ عَنْهُمْ سَيِّئَاتِهِمْ وَلَنَجْزِيَنَّهُمْ أَحْسَنَ الَّذِى كَانُواْ يَعْمَلُونَ ]

(5. Whoever hopes in meeting with Allah, then Allah's term is surely coming, and He is the All-Hearer, the All-Knower.) (6. And whosoever strives, he strives only for himself. Verily, Allah stands not in need of any of the creatures. ) (7. Those who believe, and do righteous good deeds, surely, We shall expiate from them their evil deeds and We shall indeed reward them according to the best of that which they used to do.)
