Takadu tamayyazu mina alghaythi kullama olqiya feeha fawjun saalahum khazanatuha alam ya'tikum (surah Mulk: 8)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(67:8) as though it will burst with rage. Every time a multitude is cast into it, its keepers will ask them: 'Did no warner come to you?' *14

Takaadu tamayyazu minal ghaizi kullamaaa uliqya feehaa fawjun sa alahum khazanatuhaaa alam yaatikum nazeer

*14) The real nature of this question will not be of a question that the keepers of Hell would like to ask them whether a warner from Allah had come to them or not, but the object would be to make them realize that no injustice had been done to them by casting them into Hell. They would try to make them confess that Allah had not kept them uninformed and unwarned: He had sent the Prophets to them; He had informed them of the truth and of the Right Way; He had warned them that if they followed a way other than the Right Way, it would lead them to Hell, in which they had been cast. But they had not listened to the Prophets. Hence, they rightly deserved the punishment which was being meted out to them at that time.
This thing has been pointed out over and over again in the Qur'an that the test for which Allah has sent man in the world is not being conducted by keeping man absolutely unaware and uninformed of the requirements of the test only to see whether he found the right way by himself or not; but Allah has made the most appropriate arrangements that could possibly be trade of guiding him to the Right Way, and it is that He has raised the Prophets and sent down the Books. Now the test of man lies in this whether he accepts the Prophets and the Books brought by them and adopts the straight way, or turns away from them to follow his own desires, whites and speculations. Thus, the Prophethood, in fact, is Allah's argument which He has established against tnan and on its acceptance or rejection depends his whole future life. No one, after the appointment of the Prophets, can present the excuse that he remained unaware of the Truth, or that he has been caught and put to the hard test unawares, or that he is being punished while he was innocent. This theme has been presented in countless different ways in the Qur'an; for instance, see AI-Baqarah: 213, and E.N. 230 on it; An-Nisa': 41-42, 165 and E N.'s 64 and 208; Al-An`am: 130-131, and E.N.'s 98-100; Bani Isra'il: 15 and E.N. 17; Ta Ha: 134; Al-Qasas 47, 59, 65 and E.N.'s 66, 83; Fatir: 37; AlMu'min: 50 and E.N. 66.
