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 made the sky a secure canopy; and yet they turn away from these Signs. 32 It is He Who created the night and the day, and the sun and the moon. Each of them is floating in its 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 soul must taste of death, and We try you with evil and with good, for ordeal. And unto Us ye will be returned. 35 And when those who disbelieve see you, [O Muhammad], they take you not except in ridicule, [saying], "Is this the one who insults your gods?" And they are, at the mention of the Most Merciful, disbelievers. 36 Man was created of haste, surely I shall show you My signs, so ask Me not to hasten. 37 Yet they say: "When will the promised threat come to pass, if you speak the truth?" 38 If those who disbelieved but knew the time when they will not avert the Fire from their faces or from their backs and they will not be aided... 39 Nay, but [the Last Hour] will come upon them of a sudden, and will stupefy them: and they will be unable to avert it, and neither wilt they be allowed any respite. 40 And indeed, [O Muhammad, even] before thy time have [God's] apostles been derided - but those who scoffed at them were [in the end] overwhelmed by the very thing which they had been wont to deride. 41
