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 We established the heaven as a well protected roof, yet they still turn away from its signs. 32 It is God who has created the night, the day, the Sun, and Moon and has made them swim in a certain orbit. 33 And We appointed not for any human being before thee immortality; if thou then diest, are they to be immortals? 34 Every soul will know the taste of death. We tempt you with evil and with good as a trial; and to Us you will 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 was created of haste, surely I shall show you My signs, so ask Me not to hasten. 37 And they say, "When is this promise, if you should be truthful?" 38 If only those who deny the truth knew the time when they would not be able to ward off the fire neither from their faces nor from their backs. They will not 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, [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
