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 As they come hurrying on in fear, their heads upraised, their gaze returning not to them, and their hearts as air. 43 (O Muhammad), warn mankind of the Day when a severe chastisement shall overtake them, and the wrong-doers will say: "Our Lord, grant us respite for a short while; we shall respond to Your call and will follow Your Messengers." (But they will be clearly told): "Are you not the same who swore earlier that they shall never suffer decline?" 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 Mighty indeed were the plots which they made, but their plots were (well) within the sight of Allah, even though they were such as to shake the hills! 46 So think not that Allah will fail to keep His Promise to His Messengers. Certainly, Allah is All-Mighty, - All-Able of Retribution. 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 Mujrimun (criminals, disbelievers in the Oneness of Allah Islamic Monotheism, polytheists, disobedient to Allah, etc.) that Day bound together in fetters; [Muqarranun in fetters; mean:- with their hands and feet tied to their necks with chains.] 49 clothed in garments of black pitch, with fire veiling their faces. 50 That Allah may requite each soul according to its deserts; and verily Allah is swift in calling to account. 51 Here is a Message for mankind: Let them take warning therefrom, and let them know that He is (no other than) One Allah: let men of understanding take heed. 52
