Have not these who disbelieve considered that the heavens and the earth were closed up, then We rent them? And We have made of water everything living; will they not then 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 We established the heaven as a well protected roof, yet they still turn away from its signs. 32 And He it is Who created the night and the day, and the sun and the moon. They float, each in an orbit. 33 AND [remind those who deny thee, O Prophet, that] never have We granted life everlasting to any mortal before thee: but do they, perchance, hope that although thou must die, they will live forever?" 34 Every living being must taste death; and We test you with harm and with good – a trial; and to Us only you have to return. 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: soon (enough) will I show you My Signs; then ye will not ask Me to hasten them! 37 They say, 'And when shall the promise come to pass, if you speak truly?' 38 If the unbelievers only knew when they will be unable to shield either their faces or their backs from the Fire; when they will not be helped! 39 Indeed, it will come upon them suddenly and confound them; and they will not be able to ward it off, nor shall they be reprieved. 40 And assuredly mocked were the apostles before thee, then there surrounded those of them who scoffed that whereat they had been mocking! 41
