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 have made the heavens as a canopy well guarded: yet do they turn away from the Signs which these things (point to)! 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 And before you, We did not appoint on earth a never-ending life for any human; will they, if you depart, become immortal? 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 those who deny the truth see you, they laugh at you, saying, "Is this the one who talks of your deities?" Yet it is they who deny all mention of the Gracious One. 36 Man is a creature of haste; [but in time] I shall make obvious to you [the truth of] My messages: do not, then, ask Me to hasten [it]! 37 They say: "(Tell us) when will the threat of punishment come to pass if you are truthful?" 38 If only the disbelievers realised the time when they will not be able to stop the fire from their faces and from their backs – and nor are they to be helped. 39 It will come upon them unawares confounding them, and they will not be able to keep it back, nor will they be given respite. 40 And indeed the Noble Messengers before you were mocked at, but their mockery ruined the mockers themselves. 41
