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 when they shall run with their necks outstretched and heads erect, their glances never return to themselves, their hearts are empty. 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 You lived in the dwellings of those who wronged themselves, even though it was made clear to you how We dealt with them. We also showed you examples." 45 They hatched their plots; but these plots were all within God's knowledge. Though their plots were such as to shake the mountains, God will bring their plots to nothing. 46 HENCE, do not think that God will fail to fulfil the promise which He gave to His apostles: verily, God is almighty, an avenger of evil! 47 The day when the earth will he replaced by some other than the earth, as will be the skies, and every one will appear before God the one and omnipotent, 48 Thou wilt see the guilty on that day linked together in chains, 49 Their garments of liquid pitch, and their faces covered with Fire; 50 That Allah may requite each person according to what he has earned. Truly, Allah is Swift at reckoning. 51 This is a preaching for mankind, and that they may be warned thereby, and that they may know that there is only one God, and that the men of understanding may be admonished. 52
