(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 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 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 They plotted their plots, but their plots are (known) to Allah, even though their plots were such as to move mountains. 46 So do not ever assume that Allah will not fulfil His promise to His Noble Messengers; indeed Allah is the Dominant, the Avenger. 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 On that Day you shall see the guilty bound in chains, 49 Their cloaks will be of pitch and fire will cover their faces. 50 God will requite each soul according to its deeds. Swift is God's reckoning. 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
