(Muhammad), do not think that God is unaware of what the unjust people do. He only gives them a respite until the day when the eyes will stare fixedly, 42 (And) they would hasten forward, heads lifted upwards, gazes fixed, and emptied out their hearts. 43 And, [O Muhammad], warn the people of a Day when the punishment will come to them and those who did wrong will say, "Our Lord, delay us for a short term; we will answer Your call and follow the messengers." [But it will be said], "Had you not sworn, before, that for you there would be no cessation? 44 And yet, you dwelt in the dwelling-places of those who had sinned against their own selves [before your time,] and it was made obvious to you how We had dealt with them: for We have set forth unto you many a parable [of sin, resurrection and divine retribution]." 45 Still they are plotting their plots, but evident are their plots to God, even though they are so adroit as to make the mountains move. 46 So, do not think, (O Prophet), that Allah will go back upon His promise to His Messengers. Surely Allah is Mighty, Lord of retribution. 47 On the day when the earth and the heavens will be replaced by another earth and heavens and everyone will be brought before the One Almighty God, 48 Thou wilt see the guilty on that day linked together in chains, 49 their garments shall be of melted tar, and their faces enveloped by the Fire. 50 that God may recompense every soul for its earnings; surely God is swift at the 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
