Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe? 30 We set firm mountains upon the earth lest it should sway under them, and We placed therein passages for paths so that they might find their way. 31 And We have made the heaven a roof, safe and well guarded. Yet they turn away from its signs (i.e. sun, moon, winds, clouds, etc.). 32 It is He who created the night and the day, the sun and the moon, each swimming in a sky. 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 soul shall taste of death; and We try you with evil and good for a testing, then unto Us you shall be returned. 35 And when those who disbelieve (in the Oneness of Allah) see you (O Muhammad SAW), they take you not except for mockery (saying): "Is this the one who talks (badly) about your gods?" While they disbelieve at the mention of the Most Beneficent (Allah). [Tafsir. Al-Qurtubi]. 36 Man is made of haste. I shall show you My portents, but ask Me not to hasten. 37 They say, 'And when shall the promise come to pass, if you speak truly?' 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, but it shall come upon them suddenly, dumbfounding them, and they shall not be able to repel it, nor shall they be respited. 40 Messengers before thee, indeed, were mocked, but that whereat they mocked surrounded those who scoffed at them. 41
