Deem not that God is heedless of what the evildoers work; He is only deferring them to a day when eyes shall stare, 42 when they shall keep pressing ahead in haste, their heads lifted up, their gaze directed forward, unable to look away from what they behold, their hearts utterly void. 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 Yet you dwelt in the dwellings of those who had exceeded themselves, and it was evident to you how We had dealt with them; and We held out examples before you." 45 They devised evil plans which were so sinful that even the mountains could not endure them. All these were known to God. 46 Think not that God would go back on His promise (made) to the apostles. Indeed God is mighty, the Lord 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 And thou wilt see the sinners that day bound together in fetters;- 49 their garments shall be of melted tar, and their faces enveloped by the Fire. 50 That Allah may requite each soul according to its deserts; and verily Allah is swift in calling to account. 51 This (Quran) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilah (God - Allah) - (none has the right to be worshipped but Allah), and that men of understanding may take heed. 52
