And never think that Allah is unaware of what the wrongdoers do. He only delays them for a Day when eyes will stare [in horror]. 42 Racing ahead, their heads raised up, their glance does not come back to them, and their hearts are void. 43 Warn mankind of the Day when the punishment will overtake them, when the evildoers will say: 'Our Lord, grant us respite for awhile, we will answer Your call, and follow the Messengers' Did you not once swear that you would never cease? 44 You lived in the dwellings of those who wronged themselves, and it was clear to you how We dealt with them, and how We struck parables for you. 45 Indeed the unbelievers contrived their plan, but it is in Allah's power to nullify their plan, even though their plans were such that would move even mountains. 46 Do not think that Allah will break the promise He gave to His Messengers. Mighty is Allah, and Vengeful. 47 One day the earth will be changed to a different earth, and so will be the heavens, and (men) will be marshalled forth, before Allah, the One, the Irresistible; 48 And you will see the criminals that Day bound together in shackles, 49 with garments of pitch and faces covered by fire. 50 so that Allah may requite each person for his deeds. Allah is swift in reckoning. 51 This is a message for mankind that they may take a warning from it, and may know that He is the one and only God, and that men of wisdom may reflect. 52
