١٢. وَلَوْ تَرَىٰٓ إِذِ ٱلْمُجْرِمُونَ نَاكِسُوا۟ رُءُوسِهِمْ عِندَ رَبِّهِمْ رَبَّنَآ أَبْصَرْنَا وَسَمِعْنَا فَٱرْجِعْنَا نَعْمَلْ صَـٰلِحًا إِنَّا مُوقِنُونَ
١٣. وَلَوْ شِئْنَا لَـَٔاتَيْنَا كُلَّ نَفْسٍ هُدَىٰهَا وَلَـٰكِنْ حَقَّ ٱلْقَوْلُ مِنِّى لَأَمْلَأَنَّ جَهَنَّمَ مِنَ ٱلْجِنَّةِ وَٱلنَّاسِ أَجْمَعِينَ
١٤. فَذُوقُوا۟ بِمَا نَسِيتُمْ لِقَآءَ يَوْمِكُمْ هَـٰذَآ إِنَّا نَسِينَـٰكُمْ ۖ وَذُوقُوا۟ عَذَابَ ٱلْخُلْدِ بِمَا كُنتُمْ تَعْمَلُونَ
[12-14] Would22 that you could see the criminals when they will be standing before their Lord with hanging heads. (Then they will be saying: "Our Lord, we have indeed seen and heard: now send us back so that we may act righteously: we are now convinced." (In reply it will be said :) "Had We so willed We would have given every soul its guidance from the beginning,23 but the Word of Mine, which I had said, has been fulfilled that I shall fill Hell with jinns and men,24 all together. So, taste now the recompense of your having forgotten the meeting of this Day.25 We, too, have forgotten you now! Taste the everlasting torment in consequence of your misdeeds."
22This will be the scene when after returning to its Lord the human 'ego' will be standing before Him to render an account of its deeds.
23That is, "Had it been Our will w give guidance to the people after having made them observe and experience the reality, We would not have brought you here after making you undergo this hard test in the world. We could have given you such guidance even before. But We had a different scheme for you from the very beginning. We wanted to test you by keeping the reality hidden from your eyes and senses in order to see whether you could recognize it by your intellect after perceiving its signs in the universe and in your own selves or not, whether you could take advantage of the help that We provided to you through Our Prophets and Our Books to recognize the reality or not, and whether after knowing the reality you could attain such control over your self or not that you should free yourselves from the service of your desires and lusts and believe in the reality and mend your ways and attitudes accordingly. You have failed in this test. Now setting the same test once again will be useless. If the second test is set in a condition when you remember everything that you have seen and heard here, it will be no test at all. And if, like before, you are given re-birth in the world, while you do not remember anything and the reality is kept hidden from you, and you are set the test once again as before the result will not be, any different. " (For further explanation, sec Al-Baqarah: 210, Al-An`am: 7-9, 27-28, 158; Yunus: 19; AI-Mu'minun: 99-100).
24The allusion is to what Allah had said, addressing Satan, at the creation of Adam: In vv. 69-88 of Surah Sad the whole story of that time has been related. When Satan refused to prostrate himself before Adam and asked for respite till Resurrection in order to seduce mankind, Allah had replied: "The truth is this, and the truth only I speak, that I shall fill Hell with you and all those who follow you from among mankind. "
The word ajma'in (all together) here does not mean that all jinns and all men will be cast into Hell, but it means that the satans and the men who follow them, will be cast into Hell all together.
25That is, "You became so absorbed in pleasure-seeking in the world that you totally forgot that you had to meet your Lord on this Day."
