(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 Hastening forward, their heads upraised, their eyes not reverting to them and their hearts vacant. 43 Hence, warn men of the Day when this suffering may befall them, and when those who did wrong [in their lifetime] will exclaim: "O our Sustainer! Grant us respite for a short while, so that we might respond to Thy call and follow the apostles!" [But God will answer:] "Why - were you not aforetime wont to swear that no kind of resurrection and retribution awaited you? 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 Indeed, they planned their plot, and their plot was with Allah, though their plot was a great (one, still) it would never be able to remove the mountains (real mountains or the Islamic law) from their places (as it is of no importance) [Tafsir Ibn Kathir, Vol. 2, Page 597]. [It is said by some interpreters regarding this Verse that the Quraish pagans plotted against Prophet Muhammad SAW to kill him but they failed and were unable to carry out their plot which they plotted]. 46 Think not that God would go back on His promise (made) to the apostles. Indeed God is mighty, the Lord of retribution. 47 The day when the earth will he replaced by some other than the earth, as will be the skies, and every one will appear before God the one and omnipotent, 48 And thou wilt see the sinners that day bound together in fetters;- 49 clothed in garments of black pitch, with fire veiling their faces. 50 That God may reward each soul for its deeds. Indeed God is swift at reckoning! 51 This is a message for mankind that they may take a warning from it, and may know that He is the one and only God, and that men of wisdom may reflect. 52
