(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 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 lived among the dwellings of those who wronged themselves, and it had become clear to you how We dealt with them. And We presented for you [many] examples." 45 And [this retribution will befall all evildoers because] they devise that false imagery of theirs - and all their false imagery is within God's knowledge. [And never can the blasphemers prevail against the truth - not] even if their false imagery were so [well devised and so powerful] that mountains could be moved thereby. 46 Never think that God will fail in His promise to His messengers. God is mighty and capable 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 For on that Day thou wilt see all who were lost in sin linked 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 message for mankind. Let them take warning from it and know that He is but one God. Let those possessed of understanding may take heed. 52
