Translation of the verse 71 from Surah Az-Zumar : Number of verses 75 - - page 466 - Part 24.
And those who disbelieved will be driven to Hell in groups, till, when they reach it, the gates thereof will be opened (suddenly like a prison at the arrival of the prisoners). And its keepers will say, "Did not the Messengers come to you from yourselves, reciting to you the Verses of your Lord, and warning you of the Meeting of this Day of yours?" They will say: "Yes, but the Word of torment has been justified against the disbelievers!"
And those who disbelieved will be driven to Hell in groups until, when they reach it, its gates are opened and its keepers will say, "Did there not come to you messengers from yourselves, reciting to you the verses of your Lord and warning you of the meeting of this Day of yours?" They will say, "Yes, but the word of punishment has come into effect upon the disbelievers.
(39:71) (After the judgement has been passed) the unbelievers shall be driven in companies to Hell so that when they arrive there, its gates shall be thrown open *81 and its keepers shall say to them: 'Did Messengers from among yourselves not come to you, rehearsing to you the Signs of your Lord and warning you against your meeting of this Day?' They will say: 'Yes indeed; but the sentence of chastisement was bound to be executed against the unbelievers.'
*81) That is, the gates of Hell will not have already been opened but will be opened on their arrival there just as the gate of a prison is opened on the arrival of the culprits and is closed as soon as they have entered it.
