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 their necks outstretched and heads erect, their glances never return to themselves, their hearts are empty. 43 And warn (O Muhammad SAW) mankind of the Day when the torment will come unto them; then the wrong-doers will say: "Our Lord! Respite us for a little while, we will answer Your Call and follow the Messengers!" (It will be said): "Had you not sworn aforetime that you would not leave (the world for the Hereafter). 44 And you dwell in the abodes of those who were unjust to themselves, and it is clear to you how We dealt with them and We have made (them) examples to you. 45 They devised their devising, and their devising is known to God; though their devising were such as to remove mountains.' 46 So think not that Allah will fail to keep His Promise to His Messengers. Certainly, Allah is All-Mighty, - All-Able of Retribution. 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 Thou wilt see the guilty on that day linked together in chains, 49 with garments of pitch and faces covered by fire. 50 This is how God will recompense each soul for its deeds. God's reckoning is swift. 51 This is the message to be conveyed to all mankind – and in order to warn them with it, and for them to know that He is the only One God, and for men of understanding to heed advice. 52
