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 They will hurry on in fright, their heads lifted up, their gaze directed forward, their minds utterly void. 43 And warn mankind of the day when the chastisement comes on them, And those who did evil shall say, 'Our Lord, defer us to a near term, and we will answer Thy call, and follow the Messengers.' 'Ah, but did you not swear aforetime there should be no removing for you? 44 And (have ye not) dwelt in the dwellings of those who wronged themselves (of old) and (hath it not) become plain to you how We dealt with them and made examples for you? 45 They devised their devising, and their devising is known to God; though their devising were such as to remove mountains.' 46 So do not deem that God will fail in His promise to His Messengers; surely God is All-mighty, Vengeful. 47 On the Day whereon the earth will be changed into other than the earth, and the heavens also; and all creatures will appear unto Allah, the One, the Subduer. 48 For on that Day thou wilt see all who were lost in sin linked together in fetters, 49 Their cloaks will be of pitch and fire will cover their faces. 50 That Allah may requite each soul according to that which he hath earned: verily Allah is swift in 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
