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 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 from the signs thereof they are averters. 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 We appointed not for any human being before thee immortality; if thou then diest, are they to be immortals? 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 When the unbelievers see you, they take you only for mockery, saying: 'Is this he who talks about your gods' While they are unbelievers in the Remembrance of the Merciful. 36 Man is made of haste. I shall show you My portents, but ask Me not to hasten. 37 And they say: When will this promise (be fulfilled), if ye are truthful? 38 If those who disbelieved but knew the time when they will not be able to drive off the fire from their faces and from their backs, and 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 Other messengers have been mocked before you, but those who scoffed were overwhelmed by the very thing they had mocked. 41
