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 necks outstretched and heads erect, their glances never returned on themselves, their hearts void. 43 (Muhammad), warn the people of the day when torment will approach them and the unjust will say, "Lord, give us respite for a little time so that we may answer your call and follow the Messengers." (The answer to their prayer will be), "Did you not swear before that you would never perish? 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 devised their devising, and their devising is known to God; though their devising were such as to remove mountains.' 46 So never think that Allah will fail in His promise to His messengers. Indeed, Allah is Exalted in Might and Owner of Retribution. 47 Upon the day the earth shall be changed to other than the earth, and the heavens and they sally forth unto God, the One, the Omnipotent. 48 Thou wilt see the guilty on that day linked together in chains, 49 Their shirts made of pitch and the fire covering their faces 50 That Allah may requite each soul (according to) what it has earned; surely 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
