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 (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 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 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 Think not that God would go back on His promise (made) to the apostles. Indeed God is mighty, the Lord of retribution. 47 [His promise will be fulfilled] on the Day when the earth shall be changed into another earth, as shall be the heavens and when [all men] shall appear before God, the One who holds absolute sway over all that exists. 48 And thou wilt see the sinners that day bound together in fetters;- 49 Of molten pitch shall be their garments, their faces covered with flames, 50 Allah will recompense each soul according to its earnings. Swift is the Reckoning of Allah. 51 This is a clear message for mankind in order that they may be warned thereby, and that they may know that He is only One Allah, and that men of understanding may take heed. 52
