So taste [punishment] because you forgot the meeting of this, your Day; indeed, We have [accordingly] forgotten you. And taste the punishment of eternity for what you used to do."
The Bad State in which the Idolators will be on the Day of Resurrection
Allah tells us the state of the idolators on the Day of Resurrection and what they will say when they see the Resurrection and are standing before Allah -- may He be glorified -- humiliated and brought low, with their heads bowed, i.e., in shame. They will say:
رَبَّنَآ أَبْصَرْنَا وَسَمِعْنَا
(Our Lord! We have now seen and heard,) meaning, `now we hear what You say and we will obey You.' This is like the Ayah,
أَسْمِعْ بِهِمْ وَأَبْصِرْ يَوْمَ يَأْتُونَنَا
(How clearly will they see and hear, the Day when they will appear before Us!) (19:38). And they will blame themselves when they enter the Fire, and will say:
In verse 11, it was said: قُلْ يَتَوَفَّاكُم مَّلَكُ الْمَوْتِ الَّذِي وُكِّلَ بِكُمْ (Say, "The angel of death who has been assigned for you will take you in full" -11). In the verse previous to it, the deniers of the Qiyamah were warned and an answer was given to their wondering as to how would they be brought back to life once again after they had died and become dust. In the verse cited above, such people are being reminded, 'Think of your death which is, in itself, a great manifestation of the perfect power of Allah Ta’ ala. Your heedlessness and ignorance make you think that one's death comes all by itself, just like that. This is not how it is. In fact, fixed for your death there is a time with Allah and for this there is a standing system run through angels. Sayyidna ` Izra'il (علیہ السلام) is the foremost among them, the one who is the master-manager of death throughout the world. Whenever and wherever a person is destined to die, it is precisely at that time that he draws out his soul from his body.' This is what has been stated in the cited verse. It should be noted that مَلَکُ المَوت (malakul maut: angel of death) has been mentioned in the singular form. It means Sayyidna ` Izra'il (علیہ السلام) . Please compare it with another verse where it is said: الَّذِينَ تَتَوَفَّاهُمُ الْمَلَائِكَةُ (the ones to whom the angels brought death - 16:28).
Man’s creation for the first time is enough to convince mankind of the possibility of creation for the second time. But when a man does not believe in his accountability before God, he ridicules the possibility of a second creation, and he talks flippantly of it. But, this amounts to taking liberties throughout the period of freedom given for the purpose of putting man to test. And when this period expires and a man dies and is made to stand before Almighty God for the purpose of giving an account of himself, he will find himself speechless. At that time, the arrogant will say that they now accept the reality and will request that they be sent back into the world, so that they may perform righteous deeds. But this admission at that stage will be useless. Had God desired that people should accept reality in this way, He could have compelled them to accept it in the present world itself. Before God, that acceptance carries weight which is made without the reality being visible. Acceptance after seeing the reality has no value.
