Deem not that God is heedless of what the evildoers work; He is only deferring them to a day when eyes shall stare, 42 the while they will be running confusedly to and fro, with their heads upraised [in supplication,] unable to look away from what they shall behold, and their hearts an abysmal void. 43 So warn mankind of the Day when the Wrath will reach them: then will the wrong-doers say: "Our Lord! respite us (if only) for a short term: we will answer Thy call, and follow the messengers!" "What! were ye not wont to swear aforetime that ye should suffer no decline? 44 "And ye dwelt in the dwellings of men who wronged their own souls; ye were clearly shown how We dealt with them; and We put forth (many) parables in your behoof!" 45 And they have indeed planned their plan, but their plan is with Allah, though their plan was such that the mountains should pass away thereby. 46 So think not that Allah will fail to keep His promise to His messengers. Lo! Allah is Mighty, Able to Requite (the wrong). 47 (Do warn them of the) Day when the heavens and the earth shall be altogether changed; when all will appear fully exposed before Allah, the One, the Irresistible! 48 And on that day you will see the guilty linked together in chains. 49 Their raiment of pitch, and the Fire covering their faces, 50 That God may reward each soul for its deeds. Indeed God is swift at reckoning! 51 This (Quran) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilah (God - Allah) - (none has the right to be worshipped but Allah), and that men of understanding may take heed. 52
