Upon the day when We shall muster out of every nation a troop of those that cried lies to Our signs, duly disposed, 83 until, when all of them have arrived, Allah will say: "Did you give the lie to My Signs even without encompassing them with your knowledge? If that is not so, what did you do?" 84 And the decree will befall them for the wrong they did, and they will not [be able to] speak. 85 Observe they not that We have appointed the night that they may repose therein, and the day sight-giving? Verily herein are signs unto a people who believe. 86 And [warn of] the Day the Horn will be blown, and whoever is in the heavens and whoever is on the earth will be terrified except whom Allah wills. And all will come to Him humbled. 87 You see the mountains and think them firmly fixed. But they shall pass away as the clouds pass away. Such is the work of God, who has ordered all things to perfection: He is fully aware of what you do. 88 Whoever brings good, he shall have better than it; and they shall be secure from terror on the day. 89 and those who do evil will be flung down on their faces in the Fire. Are you not rewarded according to your deeds? 90 (Say): I (Muhammad) am commanded only to serve the Lord of this land which He hath hallowed, and unto Whom all things belong. And I am commanded to be of those who surrender (unto Him), 91 to recite the Quran." Whoever follows its guidance, follows it only for the good of his own soul; and as for him who goes astray, just say, "I am only a warner." 92 And say: Praise be to Allah, He will show you His signs so that you shall recognize them; nor is your Lord heedless of what you do. 93
