Deem not that Allah is unaware of what the wicked do. He but giveth them a respite till a day when eyes will stare (in terror), 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 you dwelt in the dwellings of men who wronged themselves, and it was clear to you how We had dealt with them. And We put forth (many) 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 So do not deem that God will fail in His promise to His Messengers; surely God is All-mighty, Vengeful. 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 sinners coupled together in fetters; 49 Their trousers shall be of pitch, and the Fire shall cover their faces. 50 This is how God will recompense each soul for its deeds. God's reckoning is swift. 51 This is a proclamation for all mankind that they may be warned by it, and that they may know that their God is none but the One True God, and that men of understanding may take heed. 52
