Have the unbelievers not seen that the heavens and the earth were sewn up as one (solid) mass, then We unstitched them, and that We made every living thing of water? 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 set up the heaven as a roof well-protected; yet still from Our signs they are turning away. 32 It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course. 33 We have never assigned immortality to a human before you, therefore, if you yourself die, will they live for ever? 34 Every soul shall taste death. We will try you with a trial of evil and good. Then, to Us you shall be returned. 35 When the unbelievers see you, they take you only for mockery, saying: 'Is this he who talks about your gods' While they are unbelievers in the Remembrance of the Merciful. 36 Man is hasty by nature. I shall certainly show you My Signs. Do not ask Me to be hasty. 37 They say: 'If you are truthful, when will this promise come' 38 If only the unbelievers could apprehend the moment when they would neither be able to ward off the fire from their faces and their backs, nor help reach them! 39 Nay, it may come to them all of a sudden and confound them: no power will they have then to avert it, nor will they (then) get respite. 40 And indeed the Noble Messengers before you were mocked at, but their mockery ruined the mockers themselves. 41
