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 set in the earth firm mountains lest it should shake with them, and We set in it ravines to serve as ways, that haply so they may be guided; 31 And we have made the sky a roof withheld (from them). Yet they turn away from its portents. 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 given no man everlastingness before you. So then if you die, will they live ever after? 34 Every human being is bound to taste death; and We test you [all] through the bad and the good [things of life] by way of trial: and unto Us you all must return. 35 And when those who disbelieve behold thee, they but choose thee out for mockery, (saying): Is this he who maketh mention of your gods? And they would deny all mention of the Beneficent. 36 Man was created of haste. Assuredly I shall show you My signs; so demand not that I make haste. 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 If the unbelievers but knew when that they shall not ward off the Fire from their faces nor from their backs, neither shall they be helped! 39 Nay, it (the Fire or the Day of Resurrection) will come upon them all of a sudden and will perplex them, and they will have no power to avert it, nor will they get respite. 40 Indeed (many) Messengers were mocked before you (O Muhammad SAW), but the scoffers were surrounded by that, whereat they used to mock. 41
