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 [that] We have set up the sky as a canopy well-secured? And yet, they stubbornly turn away from [all] the signs of this [creation,] 32 It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course. 33 (O Muhammad), We did not grant everlasting life to any human being even before you. If you were to die, will they live for ever? 34 Every soul will taste death. And We test you with evil and with good as trial; and to Us you will be returned. 35 And when those who disbelieve behold thee they only take thee up for mockery: is this he who mentioneth your gods? while in the mention of the compassionate they are themselves blasphemers. 36 Man is a creature of haste. Soon I will show you My signs, but do not ask Me to hasten them. 37 They say: "(Tell us) when will the threat of punishment come to pass if you are truthful?" 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, it shall come on them all of a sudden and cause them to become confounded, so they shall not have the power to avert 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
