Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? 30 And We have placed in the earth firm mountains lest it should move away with them, and We placed therein passages for paths, that haply they may be guided. 31 and We made the sky a secure canopy; and yet they turn away from these Signs. 32 It is God who has created the night, the day, the Sun, and Moon and has made them swim in a certain orbit. 33 We have never assigned immortality to a human before you, therefore, if you yourself die, will they live for ever? 34 Every soul must taste of death, and We try you with evil and with good, for ordeal. And unto Us ye will be returned. 35 And when the disbelievers see you, they do not appoint you except as an object of mockery; “Is he the one who speaks ill of your Gods?”; whereas they deny the remembrance of the Most Gracious Himself! 36 Man is a creature of haste. Soon I will show you My signs, but do not ask Me to hasten them. 37 But they [who reject My messages are wont to] ask, "When is that promise [of God's judgment] to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 38 Had those who disbelieve but known (of the time) when they shall not be able to ward off the fire from their faces nor from their backs, nor shall they be helped. 39 That will suddenly come upon them and stupefy them. They shall not be able to ward it off, nor shall they be granted any respite. 40 And already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
