Surah 39. Az-Zumar
Ayah 24 - 26
٢٤. أَفَمَن يَتَّقِى بِوَجْهِهِۦ سُوٓءَ ٱلْعَذَابِ يَوْمَ ٱلْقِيَـٰمَةِ ۚ وَقِيلَ لِلظَّـٰلِمِينَ ذُوقُوا۟ مَا كُنتُمْ تَكْسِبُونَ
٢٥. كَذَّبَ ٱلَّذِينَ مِن قَبْلِهِمْ فَأَتَىٰهُمُ ٱلْعَذَابُ مِنْ حَيْثُ لَا يَشْعُرُونَ
٢٦. فَأَذَاقَهُمُ ٱللَّهُ ٱلْخِزْىَ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا ۖ وَلَعَذَابُ ٱلْـَٔاخِرَةِ أَكْبَرُ ۚ لَوْ كَانُوا۟ يَعْلَمُونَ
[24-26] Now, how can you imagine the plight of the one who will receive the severe punishment of the Day of Resurrection on his face?44 To such wrongdoers it will be said, "Taste now (the fruit of) what you had been earning."45 Many a people before them also denied likewise. Consequently, the scourge overtook them from whence they least expected. Then Allah made them to taste disgrace even in their worldly life, but the punishment of the Hereafter is far more terrible. Would that they knew it!
44One takes a blow on one's face only when one is absolutely helpless and powerless, otherwise until one has some power to resist, one goes on receiving the blows on the other parts of one's body but saves one's face. Therefore, here the extreme state of helplessness of a person has been depicted, saying that he will receive the severe punishment on his face.
45The word kasab, in the Qur'anic terminology, implies one's descrying and earning a reward and punishment in consequence of one's actions and deeds. The real earning of a doer of good is that he becomes worthy of Allah's reward, and the earning of the evil-doer is the punishment that he will receive in the Hereafter.
